When we arrived at the air BNB we had some issues using the key for the main door of the building, but Mattia was quick to respond and we were able to get in. Once we got upstairs, we tried to use the toilet but it would not flush. We contacted Mattia immediately and he instructed us to use a bucket in the apartment to fill with water and pour into the toilet; he said the pipes were old and may need some time. We did as he directed then headed to dinner. When we got back, the toilet was still not flushing and the washer had leaking so we contacted him again and he said he would send a plumber out in the morning. We left early that morning and the toilet was still not functioning. Mattia let us know a plumber came and the toilet should be working. When we arrived home, the toilet was working for 1 flush and then stopped working again. We let him know and he said the plumber stated it was fine, so he would not do anything further. We also alerted him the washer leaked again after the second time we used it. So all in all, we had a 3 night stay at this AirBNB with a toilet that flushed one time. Mattia was unwilling to work with us to get a refund of any sort because he stated the plumber said things other than TP were flushed, however we had contacted Mattia within the first 5 minutes of being in the Air BnB that the toilet was not functioning. I will note that AirBNB provided us a courtesy credit after reviewing our correspondence with Mattia. The apartment is conveniently located and a good value (if the toilet is working) but I will also note the area is loud in the early morning and evening.
