The place is exactly how it looks in the pictures. Although it’s close to a neighborhood with a lot of homeless people, I never felt unsafe. You are in the heart of the city and close to busses and all the public transport in San Francisco.
The staff are very friendly and ready to help you.
The rooms are not big, but we honestly get only in the hostel for resting and sleeping, so honestly the space was enough for us.
We are three friends in their thirties and we really enjoyed staying at Sonder. If we are ever back, I would not hesitate in booking a room there.
