It was a very nice stay at Mario’s, very convenient & clean! Just be slightly careful when in the toilet as the floors are very slippery when wet. Also, the flood in Venice had damaged the main door leading to the compound, thus it was very, very difficult to open/close it, someone from the outside heard us and helped. However, it’s not an issue as the rooms are not on the ground floor and had extra locks, so it was still safe and quiet at night :) - don’t worry, there is an elevator! I had a bad knee but it was still good.
