Thames Inn & Marina, Groton
Charming place to stay
The area is beautiful, the Inn is older, but clean and has charm. The staff was very friendly. Loved the view of the marina.

Not what I expected
It was definitely not what I expected, I called from a Holiday Inn when told no vacancies. I called Hotels. Com hoping to find something comparable and booked my two day stay at what was not really a hotel but a motel which was old and in need of major upgrading. The good point was that the manager was very friendly and accommodating and not far from our destinations. Bed was old and not comfortable and in need of painting and maybe a few decorations.

The inn is pretty run down. The coffee maker did not work and the maker looked super dirty. The inn needs serious updating. Good place to crash if you're broke or just do not care where you sleep. It is really too bad, because the view of the Thames River is so cool.

Good stay, nice view of the water
My stay here was well worth it. It was only for one night but it was worth it. The room/building and the dock was a bit dated but it was clean. The shower was noisy and cable only had low channels but other than that it was a great stay. The water was refreshing to look at. If you are a light sleeper bring a fan or noise maker. There are boats and train tracks close by. Anywho, the room was clean and in order. The noise level from the other residents was great, wasn't loud at all. Nice Cumberland farms store less than a mile away. Not to mention, the worker Wayne was a likable guy. He was kind and courteous. My battery needed a jump and he helped me without a problem jumping my battery from his own personal car. The process took nearly 10 minutes but he was very good about the whole thing. The stay is worth it if you are not overly picky about things.
