Nice place on the water
The stay was great. The office man Wayne was a really nice guy & was very attentive to our needs. The place was nice & clean, just a little out dated, but, nice all the same. It's not a fancy place, but, we were only there for sleeping & showers for the most part. It was great to find a full kitchen there, (We love to cook) only down fall was no pots, pans, etc... & it was really nice being on the water too!

Wonderful Staff
We had booked two nights and the inn keeper helped us with something we forgot. He is very kind and accommodating to make sure your stay is perfect. We love going to Foxwoods so we will definitely be back.

Cool place to stay
The stay was good. The place is old fashioned but comfortable and right next to the river. You can watch submarines coming and going from the naval yards. The manager is very accommodating to any needs.
