My boyfriend and I choose to stay in Ace for a four days visiting in Seattle. We stayed in the shared washroom suite which doesn't bother us at all. The shower room is clean and always with nice music. Our room is not big but it's comfortable and cozy. The hotel said they gave us a more quiet room that the window is not facing the main street (1st Ave) but Wall street. But still you need ear plugs if you're sensitive to noise (they provide ear plugs in the room). Simple breakfast is nice. We didn't mind to go out and try other breakfasts in the town anyway.
The thing I love about the hotel is the look of it, no extra decorations. The neighborhood is very fun with many choices of bars and restaurants. A walkable distance to Pike Market and Downtown. Staffs at the front desk are nice.
The only one thing that bothers me more is that it is in an older building so the soundproof is not the best. Our room is very closed to the downstair restaurant's kitchen so we could hear their music sometimes. We didn't do it but if noises from downstair bother you, you could call the front desk.
