It was awful. The whole story is below.
Day 1: The beginning was unpleasant because the key was not in the key safe. Fortunately, the host arrived in 15 mins to give us the key. In the following one hour we found out that the fridge is not working so we texted to the host.
Moreover, there was only a half a roll of toilet paper, so we asked the host if it is included or not. He apologised and said that he will bring us the toilet paper as soon as he could. He did not respond to the fridge issue. Two hours later we texted him again regarding the fridge. We asked him to check the fridge.
Day 2: Almost one day later (exactly 18 hours (!!) later) we called him, sent him text messages, and wrote him on Airbnb (where we talked each other generally) and said that the fridge is still not working, and it is important for us to use it. (We are on a holiday; we would like to cool down water and avoid the food going bad. )
9 hours later (!) he could only say that he does not understand what happened because the previous guest hadn’t mentioned any problem. We asked him to come over and solve the problem. We told him when we will be at the apartment.
Day 3: 8 hours later (!) we asked him to answer us, because this situation is very unpleasant and scandalous. After that the texted us back that he did the necessary actions and exchanged the fridge.
He went in the apartment and did not ask us if it is okay for us, if we will be at home, if it is not a problem for us to go in the apartment where all the personal objects and values were. He did not inform us before he went in the apartment. This is terribly unpleasant, infuriating.
One more information to the fridge that it was rather a minibar. It was so small. And after the exchange we got a smaller one, only 3 bottle (0,33l) fitted in.
We did not even get any toilet paper, by then. It was also unpleasant that we needed to search for a supermarket already on the first day because of toilet paper.
The window faced the inner corridor; we could not change the air. The residents were loud, we woke up several times at night.
The pinnacle of it all was that we wanted to use the air conditioner and smell of homeless, pee and trash came into the room. We waited if the smell goes away after a few minutes, but it was worse.
All in all, Paolo was very unhelpful, and the apartment was awful. We do not recommend for anybody. It affected our entire vacation negatively.
