After a hiccup with a previous Airbnb (not owned by Alessandro), Alessandro responded within minutes and we were able to check-in within two hours the same day. Alessandro was incredibly accommodating, offered excellent restaurant recommendations, and frequently checked in to make sure everything was all right.
Although, being an old and historic building, the flat was immaculately clean, and in the five days staying there we did not see a single bug. The living room has a very comfortable couch, which is a must after long days of walking in the city. Each bedroom has their own bathroom, mini fridge, coffee maker and smart TVs (not once did we run out of hot water). The small touches in every room made the flat feel very welcoming and showed how much Alessandro is willing to go above and beyond all expectations.
The flats location was perfect with being at most a 20 minute walk from every tourist must see in the city.
When I come back to Florence, I will be staying with Alessandro again without question.
FYI there are a lot of stairs to reach the flat which may be hard for older people but they are worth the reward.
