I kept contacting the person in charge who would pick us up from the day before check-in. However, at the place we were supposed to meet, another person came and we waited for over 20 minutes. And every time we opened the door, the key was too difficult. And the air conditioner was too weak. They had 5 air conditioners, but they were not cool. The engineer went the next day, but it was still hot. It was very hot in Venice, so air conditioning was important to us.
