Misleading reviews for very low quality hotel

I’m not sure why this hotel has an average user rating of good. The property was poorly maintained, with trash and junk strewn in the front. The room was barrren of furniture except a bed, table with no chairs, and a precarious TV balanced on a chair. The floor was dirty underfoot. The hotel would not answer their phone and had no message service. The checkin hours are inconveniently limited to a 3 hour window. It faces a loud street and the door lock did not feel sturdy enough for the look of the neighborhood. Honestly, we have nothing good to say. For over $200 a night, I expect more.

The staff couldn’t find our room key. Sat in the room for twenty minutes before she came to tell us that we had to move. The bathroom light in our room didn’t work. The ceiling over the tub and shower looked gross! I was not sleeping there! The up side, the property manager called me personally to offer my refund.

The property was not as advertised. I do not recommend staying here, we ended up getting a different hotel at the Hampton nearby. We were charged twice for the hotel room as well and are having a hard time getting this resolved with no one answering the phone at the desk.

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.

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!

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.

No one was there to check me in. There was a phone number on door to call, but no one answered. A RESIDENT of hotel called a back up person, but after a few min I left. People walking around that looked like they were on drugs. Wonder how many rooms are for “residents”. Strongly suggest a different hotel.
