We had a great stay and the apartment was clean and close to the subway. However, one night another guest accidentally opened our locked door (all of the interior apartments in this building are air bnbs). While the incident was minor, we think that the keys/locks of the airbnbs in the building may be the same. I don't usually write negative reviews, but for solo traveling women or others concerned about safety I wanted to share my experience. Hopefully they change the locks to address this!
