Great location, pleasant staff but very noisy!
I attended a conference here and stayed in the hotel for convenience. It was a good conference venue and very handy to transportation but I would not choose to stay here again unless I was guaranteed a quiet room. I admit I am a poor sleeper. I had also arrived off a long haul overnight flight from New Zealand so was tired on arrival. I was given a room on the 4th floor overlooking Market St. The street view was entertaining but the noise at night made sleep very difficult. This was partly due to the trolley buses which run at night, but exacerbated by a protest group occupying the footpath across the road and roadworks conducted overnight at a nearby intersection. On the third night I resorted to earplugs, but was so tired by day 4 I requested a room change. The staff were obliging and offered a twin room on the 3rd floor with a partial bay view. This was definitely quieter, though there was a locked door between my room and the room next door so they could be used as adjoining rooms if required. The sound proofing between them was poor - I could hear the occupants voices and they could probably hear me Skyping! Fortunately they were quiet folk and it didn't bother me too much. I hope I didn't bother them! It would be preferable to be higher up, away from the atrium noise, and if you are a restless sleeper do request a bayside room, though the receptionist said requests cannot be guaranteed... 
Service was generally of a very good standard. The Concierge staff were great, with helpful suggestions about transport etc. The architecture was impressive, albeit a bit dated, and the rooms were spacious although rather beige... The heating unit was noisy so I turned it off at bedtime. The bathroom setup was adequate with a generous vanity space. There was no minibar but there is a nice deli/wineshop across the road which is open till midnight.
All up, if you are a sound sleeper you will probably enjoy your stay here, but if you are a restless sleeper, beware. And if you book without prepaying and are from overseas you might be surprised by the $35 occupancy charge per night which is added to your quoted room rate!
