The apartment (which is very small) was in a great neighborhood and a nice building. However, on one of our nights returning to the apartment, we opened the front door (which locks by a code) to find a drunk homeless man sleeping inside. This was terrifying to say the least - we didn't know what to do but step over him and hope he didn't do anything as we unlocked the inner door.

I brought this concern up with the host and she said this was not her fault and refused to refund us for one night of our stay as a compensation, telling me that we had enjoyed the apartment and that was that. I think that's a very unprofessional way to handle a guest complaint.
