Very nice, clean place but no restaurant or continental breakfast offered. Very convenient to cruise port and very organized in getting people shuttled to the port. Would definitely stay again.

We booked the room 2 months in advance.. when we arrived the room was not ready but the staff put us on a calling list and called us an hour later while we were down at Pike Place market telling us our room was ready. However, when we went to fill in the paperwork at the front desk, we were told that there would be no hot water between 8pm and 5 AM. We booked the room because we were going to a concert nearby and they neglected to tell us anything about this water outage when we first got to the hotel while we were at Pike Place market waiting for this room that would eventually we would be told have no hot water then we were told abruptly that there would be no refunds due to our booking. The manager had to come over and sort it all out suffice is to say I would never recommend this hotel to anybody again.
