The hotel is extremely dated, there was mold in the bathroom and there were numerous ants crawling along one of the bed side tables. The rooms also did not have a dead bolt lock, just a standard lock on the doorknob which made me feel incredibly unsafe. Overall, I did not think the hotel matched the description on Expedia and I would not return to this property.

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.

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!

Our room was right on the river across from Boldt Castle. Amazing view! The room itself was adequate and newly renovated. The bathroom needs updating though. The hotel is walking distance from restaurants and shops. Would stay again.
