Staying at Sonder made arriving in Washington DC so easy for me. Well located in Downtown with easy access to public transportation and overall the place is just nice. Has all the amenities you need: comfy bed, well equipped kitchen(ette), clean bathroom, stable wifi. If you reach out to them via app they react immediately. We always found a solution within hours, sometimes even minutes. Big plus for me: The little in-house gym.
So if you can afford it, go for it!
