Due to the fact that we got back, very disappointed, this will be a slightly longer evaluation.
The apartment is situated in a very good area in the city center. Everything was clean and well equipped.
But, the first bad impression was, that the apartment was not at the address we were told in advance. Secondly, we arrived in our room and the window blinds were chained together with a lock! The hostess told us that it would be "dangerous" to open it, which is hard to believe in this area. It opens a lot of room for speculations... So in fact, there was no sunlight at all, we felt like in a basement.
Communication was hard due to language problems...
Especially bad was our experience with the luggage storage after check-out offered by the hosts. We made an appointment for a certain time. One host said, that they will be there and open the door but the other host seemed to be not informed about our appointment.
So no one was opening the door at the time we agreed on. After calling them they said that it was our fault, because we could have called in advance and cannot expect them to wait the whole day.
The thing is that we made an appointment face to face and no one said to us that we should call before getting back to the apartment. Finally we only got our luggage back, after waiting for 20 min. because a friendly couple staying in the apartment opened the door for us.
Due to this miscommunication we lost our train to the airport. The hosts didn't get our problem at all, did not apologize and blamed us with strange arguments for everything.
