Please be careful with this listing and ask the host if the mold situation has been resolved before booking.
We were supposed to stay in this apartment for a month and were really happy about it when we first arrived. We soon discovered that the apartment had a leaking water boiler and this had caused huge water damage and mold. We had to leave the apartment on our second day, pay with our own money for a hotel and negotiate with AirBnb for three days until we were able to find another place to stay.
The hosts did organize a plumber to come and evaluate the problem, but this was not on the same day that we informed them of the situation. They expected us to stay in the apartment for another night even though we sent them pictures and they could understand the severity of the problem. For it to get that bad, the water boiler had to be leaking for a while. I think this also reflects on the hosts.
The rest of the apartment was nice, the location is excellent and we would have been really happy there.
