We could hear neighboring guests using their toilet. The bed was uncomfortable. The décor was . . . gosh.

I've been here a few times. It's really coming up to speed in terms of care and maintenance. Everything is very clean and comfortable. However, the room heat was off and it's pretty cold tonight. We've got the heat up but the room next store must be off and the cold is seeping through. We're ok but it's nippy.

The staff were excellent and the common areas were fresh and fun. We intentionally ordered the least expensive room for a quick trip, and while the anticipated small size wasn't a problem, per se, the fan blew directly onto the bed as a result, and was too strong even on low. Staff immediately brought us a stand up fan, and offered to look for a room in a different configuration. The bed and pillows were comfortable but the queen was a full. Again, quick trip, low price, no complaints. The soaps and lotions were lovely, and it was nice to have hot coffee downstairs every morning. We never made it to the craft beer hour but next time! Will return and go up a class or two in the room.

Clean, comfortable, nicely decorated. Very helpful desk staff. My only (small) quibble is that they didn't tell us when we checked in about the complementary social hour. I only saw a sign about it 15 minutes after it had finished
