Okay, but kinda dirty and mildew
Room needed some maintenance. I have visited a couple Sonders and all seem to be lacking maintenance. This room's bathroom smelled a bit mildewey. When I turned on the shower, water poured out of the shower pan, through the shower curb, and onto the rest of the floor. That solves the mystery. The shower was leaking all over the rest of the room. The leak was HUGE. There is no way that this went unnoticed. This was just a lack of maintenance.
The rest of the room was fine. It was quite small but it was comfortable. The bed was comfy and she sheets were clean. The floor looked like it needed a good mopping and scrub because it was dirty.
The property gives you a code to get in the doors instead of a key card but all of the key pads were kind of worn out.
A wonderful place for singles or couples. Not a great place for families because the rooms are small due to the premium location. However the hotel is excellent if you're going alone or just with another friend. I can't recommend it enough. The rooms are small but that's because of the lower price for the absolute top tier area it's in
Love the concept, affordability and the friendly and helpful staff. Hotels are always situated in a great cultural spot to be in. I really appreciate that.
Was gross. Had a connecting door to another room that I didn’t know about when booking. And someone was coughing and puking loudly all night

Room code didn't work right after check in, I had to go back down to front desk and wait for the code to be assigned again. Shower gadgets were poorly maintained and hot water takes too long, also cools down after a bit. Staff friendly and helpful.

Terrible stay at Sonder. Very noisy.
Our room is facing the street and is very noisy and we were unable to sleep the whole night, despite wearing the earplugs.

Not great
Place was not clean, bed was not comfortable and they folding even have a vending machine or anything. Won’t be back
The shower had been worked on a caulk drop lets. The room itself was very clean. Almost like the plumber came and stained and droppped caulk drop lets on shower and no one told the cleaning crew. As the rest of the bathroom hotel room clean. Also was not clear on booking self check in. So really not hotel it is rental
Room was spotless. Shower was great, bed was pretty comfy. Neighborhood is great. Only gripes: coffee machine was broken and room temperature control didn’t seem to work.
Second time staying at this property i actually got a better room booking through expedia. Love the sonder properties. The only thing was their was a demolition happening right out our window. We were adequately warned and they provided airplugs
