The host never showed up to let us into the apartment, and we were unable to reach him. After some frustration we started looking for a key and found it. Two days later I received a message explaining that he lost his phone.
The apartment itself was very nice - spacious, clean, and well-located. However, the wifi was not working and there was no phone connection. The temperature inside when we arrived was only 15 degrees. Due to the stress of not getting into the apartment or being able to reach the host, I would not stay at this place again.
