Were it not for an insufficient supply of keys I would give this place all five stars. There is a lock for the outside door to the street, a self locking barred gate in the courtyard, and a lock on the front door of the apartment. Due to the locked gate in the courtyard one can neither enter OR LEAVE the apartment without a key. Klara supplied one set of keys and we were three travelers. This was a royal pain in the butt and a fire hazzard. We all had to go out, or stay in, as a group. While Klara supplied a second set of keys on day 2 this was still an inconvenience for our group of three. In reading a notepad of testimonials in the apartment I noticed a prior guest had made the request. Honestly, for five dollars this shortcoming can be cured. I hope Klara does the right thing and buys a couple of extra sets of keys.
