Never again!
The apartment was not ready when we arrived at 9 in the evening. We waited 15 minutes in front of the apartment, we called many times but it was not possible to communicate. Later Paul told us, that he had a new number and the one published at airbnb was not correct anymore.
The second day when we were cocking the electricity broke down. Paul came after 30 minutes with an electrician. After one hour we could continue to cook.
As there was a strike of two metro lines the day we had our flight back to Germany, we wanted to use Paul´s offer to bring us to the airport with his own car for 25 euros. I was obvious that all the streets would have been overcrowded this day because of the strike. Pauls mother wrote us three times and each time she told us that she would come soon. After one hour she wrote us that she was not able to come anymore. So all in all we waited over one hour and had to take a taxi. We almost lost our flight by 10 minutes. Sorry, but you cannot react like this!!!
