The host did enter the apartment while I was at dinner without notifying me he was coming and did not notify me afterwards. The garage remote he had given me did not work, and I asked him if he would bring another one. He never confirmed if he would, but instead came and entered and put it on the table. Upon return I saw it and realized someone had been there. Apparently it was one of the hosts coworkers who had come, whom I do not know. I reported the incident to air BnB and discussed with the host, so hopefully it won't happen to any future guests.
This apartment is quiet, clean, and spacious. It is also very pretty and well decorated. The location is very great too. I stayed during a weekend visit, and it was very quiet through the night. I read some reviews about people saying it was sketchy to walk home alone at night, and that is accurate as the streets are very narrow in this part of town, so it gives that "back ally" feel. Generally the main streets were well populated, but the two side streets you have to take to walk home were not. I was with my husband and i still felt a little uneasy.
