We really enjoyed our stay here. The hotel is fairly new and the accommodations are nice. We stayed here with a group of friends and it was very convenient to meet in the lobby area to socialize and talk. They even have a small bar, which was also great to grab a drink and talk. Overall a great experience and... More

Stayed here for one night to see a concert at Mohegan Sun. Check in clerk was very friendly and found us a room that was ready when we arrived. Room was very clean and in excellent condition. Pool area looked very nice but we didn't get a chance to use it. Breakfast was pretty basic but fine. Would definitely stay... More

First time at this hotel and it was great stay. Wonderful staff, facility, and a great breakfast. Well appointed room and WiFi worked great. Very convenient to a Walmart if you forgot something. Easy access to many local sites on both sides of the Thames River.

My family and I came here for the end of April vacation to visit Mystic. I chose this Hilton over the one directly across from the aquarium because it had suites with a jacuzzi tub and the price was NOT in the least ridiculous! The room was super clean, and very spacious. I didn't realize there was a dial on... More

A very positive experience. Helpful staff, clean hotel and a nice room. Other notes, very quite, and properly heated without a lot of noise.... Have had experience with HGI before and was very impressed with the positive nature of the staff and the quality of the hotel itself.

I stayed here a couple of times for business and have always liked this hotel. The hotel is very clean and the breakfast is great. The beds are very comfortable! Next to the hotel is a Walmart which is convenient if you need to pick up medicine, snacks, etc. Room service was good too.

Great rooms, good location to I95 or other major roads. Rooms were large, clean and had very comfortable beds. Housekeeping was great. Has fridge and microwave in room. Only negative was auto closing bathroom door, but not a big deal. I was working too early for breakfast but there was coffee, tea and fruit out at all times. Staff at... More

This HGI was spotless in every area. The staff was uniformly pleasant, accommodating and actually cheerful. The location is convenient in every aspect. This has been the case every time I am in this area on business. Should I return on a leisure trip, I will stay here again.

I made a series of reservations for Hilton-affiliated properties for my wife, teen-aged daughter and me using Hilton Honors points, seeking two-bedded rooms. Unfortunately, for the Hilton Garden Inn Mystic Groton, I somehow failed to indicate two beds and did not notice this oversight until I arrived at the reservation desk at the hotel and found they had reserved only...
