As many have posted communication was fast and spot on, check in was super easy, and the apartment is really close to attractions and public transport, though we used the mytaxi app which was great. However we did not have hot water for 2 of our 3 nights. The first night without hot water it was too late in the evening to do anything about it, the next day we were touring early and all day so when we got back that evening and again didn't have hot water I messaged Flavio and he just asked why I didn't tell him yesterday.
Also the apartment is noisy, you hear the neighbors, their conversations, their TV's, the kids running up and down the stairs, and any other noises people made. Perhaps we just had a bad experience because I read may of the reviews and only booked because they were all positive and Flavio was a superhost.
