The staff was extremely friendly and helpful. While the place is kind of outdated, it is nostalgic in that sense. The location was great, the place was clean, the price was reasonable.

Stay was average

It was ok. The staff were good but the room was average/below. The bed was awful. The place was old and needs a bunch of updates.

We had a great time here. Close to the village. We had the indoor pool to ourselves . Not enough time outdoor pool. In our building there was only 1 other car. No restaurant or pub opened it was a Monday so needed to go into the town. The room was average but definitely dated. We stayed here years ago when our girls were very young.

The images on website do not mirror reality. It had a dirty and dilapidated feel to it. Ice machine didn’t work and rooms brought us back to the 1970’s. Would not stay here again.

Like every other review says, you’re in the middle of a marina and you see marina. The location is great for getting out and walking the town.

Great location right on the river, though access is through an industrial-looking boatyard. Good dining onsite and in town. Property itself a bit dated but still clean and enjoyable.
