We enjoyed our stay at this property. The rooms were big and clean. The property is also at a very beautiful location overlooking the Boldt Castle and the Bay.

Don’t let the run down looking outside of this hotel throw you off. Yes, it’s old but it’s also clean and comfortable. We stayed in a standard room with two double beds. And it was only for 1 night. The lady at the front desk was very helpful and friendly.

Our room was gorgeous, so clean and comfortable. We loved the in-room jacuzzi, laminated list of TV channels, and the courtyard outside of our room which was right on the water with a great view of Bolt Castle. We can't wait to stay 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.

Pool was in a separate building and you had to walk outside to get to it. Weather would impact that situation. That fact was not mentioned in write up

One star stay at over priced rates
Booked off season with a room with water view. If we wanted to look at a parking lot and marina with boats pulled for winter it was 170 US. We asked the nearly empty hotel to give us a room with clear water view. They charged an extra 95 US so I paid as water view was the only reason we stayed there. Very old, smelled of mold, room had dirty walls. Very disappointing.
