That's the worst experience we had! The host is always unavailable and so irresponsible. We had so much troubles with the apartment.
We arrived late at night and had to pick up the key from the office which is on the different street (so keep in mind you have to pay another 10€ for a taxi ride), when we arrived to the apartment we realised that the host didn't write the room number and the floor, so we had do try the key to each door in the building until we find the right one. And of course, the host didn't pick up the phone and didn't reply to our messages.
Another day we tried to get into the building, but the key has broken in 2 parts, it was like plastic. Again, we couldn't get in touch with the host and the office and no one ever helped us. We were trying to reach the host for an hour and we couldn't get into the building for an hour (it was like 8pm) and she never replied. We managed to get into the building thanks to our neighbours, and when the host finally contacted us, instead of suggesting any help she just told us to pay another 20€ for an extra key
Apart from it, the apartment on the pictures differs from what you get in fact, its a bit shabby, the cooker has only 1 working hotplate from 4 existing etc.
