Pros:
Location was really great. Very walkable to all the museums and monuments. Metro was very accessible. Georgetown is only a 15 minute walk too! Also the area is very safe.
The kitchen, tv and bathroom were all really nice.
Cons:
The first day, it took us 20 minutes to enter our room. Sonder gave us a code to type into a keypad to enter, but it simply didn't work. We had to call customer support. Somehow, after typing in the same code a hundred times, the code went through and we were able to get in. After that, we never had an issue with the keypad.
The bed material made it extremely hot to sleep in. The pillows offered no support. I woke up everyday sweating, and I would only have one sheet over me. There is no way to control the temperature, so the room was very very warm all the time. We lost a lot of sleep which really took away from the experience here.
