Communication with Sonder via email and App went well. We received code for front door and room, fortunately since there is no attendant. Rooms were nice and hotel was clean but shower in bathroom did not work properly. Shower head shot water in a stream towards the curtain and could not be adjusted. The hand held shower would not turn on - bad since this was a handicap accessible room with seat in shower.

First time in a Sonder. Takes a little to get used to the do it yourself concept. Nice place, very convenient and quiet. We arrived early, and the luggage lockers were full but the concierge kindly let us leave our bags with him and then brought them up to our room. Nice room but lacked drawers for storage. There was a plastered over patch on the ceiling but not painted. The toilet roll holder was loose. Overall enjoyed our stay.

Doesn’t live up to the pictures. First floor is actually the basement. I could hear all the cars and people walking past- they were right there outside the window. Terrible sound proofing in the halls, too. Room wasn’t in very good shape; stains on carpet, can’t close the curtains properly, water damage to the vanity in the bathroom. For such a fancy looking hotel online, the kitchen had paper plates and cups!

This was my first time staying at a Sonder property. My husband and I were very pleased with the entire experience! The entire contactless experience was very easy and straightforward. The room had a lot of character and included all the essentials. I Wait, why are we being quick? would definitely recommend them!
