The apartment is very nice located and has everything needed for the trip.
One evening the water has disappeared, we could not contact Federico, only in the morning next day he has told us that sometimes it happens. I've contacted a neighbour and he said that he was facing the same issue. There was a problem with the water-pump in the building, it was fixed in more than 24 hours. That was absolutely horrible situation because we went to the Lido di Ostia beach that day. But otherwise, everything was fine.
