Thames Inn & Marina

What guests think

At Thames Inn and Marina, guests praise the scenic riverfront setting and friendly staff, but many report dated rooms, inconsistent cleanliness, and occasional check-in or communication issues, making the experience vary widely depending on expectations and room assignment.

The location is convenient to the Navy base, New London, and Mystic, though a few guests felt the surrounding area looked run-down or dicey. Suites typically include kitchenettes and some have balconies or decks, but decor and furnishings are older, noise can travel between floors, and TV or streaming was unreliable while one review noted very fast Wi-Fi. Facilities are basic: grills and laundry are available, but the docks and grounds need work, kitchens can lack supplies, and there is no on-site dining or coffee, with several guests pointing to Paul's Pasta next door instead. Expect a budget, old-school waterfront stay with trade-offs.

I was surprised to have a small kitchenette, but only 2 plastic cups, silverware and a pot. Wood floor was not attached to anything and breaking up. The bathroom window did not shut. There was a massage chair in the room, that did not work, a table and two wood chairs. The parking lot was deteriorating and the marina was totally destroyed. The bed was comfortable, the sheets were clean and the tv worked.

I noticed there were nice grills outside which was nice, we didn't use because it was a one night stay. My husband and I would definitely stay here again.

The Thames Inn & Marina is a classic motel on the waterfront in Groton, CT. We were there to visit my son in the Navy, and it was incredibly convenient to the base. It's a more historical part of Groton but we never felt unsafe or worried about our car. We actually really enjoyed the charm of the area. Getting checked in was a bit bumpy, as our room wasn't ready, but they bent over backwards to make it right for us, and when we needed supplies in the room they delivered them right to us. The room is basic, but it has a full kitchenette, a firm bed, comfy chairs, and a clean bathroom, and really that's all we needed. The weather was delightful and we were able to leave the windows open, and outside the door you could see right over the marina to the water. Don't come here looking for the Ritz, but on the other hand you're also not having to pay Ritz prices. We have no regrets about staying here, and would do so again. It also looks like they are working hard on upgrading it, so it should only become nicer in the future. It is one of the most affordable options in the area, it's safe, it's clean, and it's in walking distance of nice restaurants. It's definitely worth staying at, in my opinion, and we enjoyed our time there and the chance we had to see our son!

This place has good points and bad points. It is right on the river, which I loved. Fascinating to watch the river traffic! The one staff we met was friendly and the room was clean and in reasonable condition for the price. It was lacking in some amenities. No tissues, no hand towels. A full kitchen with no paper towels or dish towels. The area seemed a bit dicey and there was only one nearby restaurant. But that restaurant - Paul's Pasta - was fantastic! So good and bad points.

Pros - There was a massage chair is the room which was in good working order and the toilet paper was better quality than even the major chains provide. Con’s - no stopper in the sink, no hot water to shower, not even paper plates for eating but there were eating utensils. No ice available or trays to make ice in the rooms, No wastebasket in the bathroom and no hangers in the wardrobe area.

Very dirty floors, hairs from previous guests shaving around faucet, dirty shower curtain, my child itched all night and I hope it was not bed bugs- we slept with the light on rest of the stay… Dirty kitchen table and fridge, steep stairs and no elevator. Insects stuck in bathroom ceiling, very loud AC, lots of trash outside the door, the office was in such a mess etc.

The room we were shown reeked of smoke, had an uncleaned bathroom, and was more of a crummy spare bedroom than a hotel room. Everything was worn out and filthy. How this place gets any positive reviews is a mystery. The key we were given didn't work in the door. We left after five minutes and went to a real hotel.

Room was not clean at all. There was a lid from a McDonalds cup on the kitchen floor when we first walked in, red solo cups under one of the beds, debris in one of the showers, and an ice pop wrapper on the floor of the bedroom. The two closets next to the bed smelled like someone treated them as a kennel for wet dogs. The tile floor felt like it had a think slime layer on it and our socks felt damp from walking on it. The top sheet on the bed had stains and we had to remove it. My girlfriend and I truly considered sleeping in the car.

The view with a private balcony was nice, we watched the sunset on the water. But the room was not as expected in the pictures. Super old and outdated. Small bed in what looked like an apartment.Mild odor from just age and probably smoking at one point.note horrible just didn’t smell refreshing and clean I would have rather had new furniture and look over the extra large space We did book last minute so maybe we were given what was left. Our main reason of staying was dog friendly place.

Sam at the front desk was amazing—super friendly and attentive, and definitely the highlight of my stay. The room itself had a great layout, and having a kitchen was a nice option (even though I didn’t use it). However, there was a strange smell in the room that never went away. I ended up buying Lysol to mask it, which helped a bit, but proper ventilation is definitely needed. Also, while the hotel advertises a water view, it’s important to know that it’s mostly blocked by a wire fence (for safety purposes--I get that) if you’re on the ground floor. You’ll only get a real view if you’re on the second floor. Overall, the service was excellent, but the room could use some improvements.

We had to wait to check-in because our room was not ready even thought it was 6:45 pm. The room had no windows. The heat sounded like a jet plane every time it came on. The people above our room sounded like big foot most of the night. The handles on the bathroom vanity and living room cabinets were broken. The blinds to the back door were broken. Pretty shabby to say the least. NOT what the website showed, even the word "INN" was missing from the sign outside. I would never stay there again, especially at over $100.00 per night. We actually left 1 night early and paid for the room.
