Sonder was a wonderful hole-in-the-wall hotel within walking distance to union square. The room was spotless, easy to access both the hotel and room, and it even had heating/A/C (which was not listed when I booked). The only complaint would be that the room I stayed at had it's lock glitch and I had to have it reset by the staff. But that was taken care of in 30 minutes so I am also glad the staff were responsive.
