The location of this apartment is absolutely perfect - it's 15 minutes walk from the Firenze train station, literally five minutes from the Duomo. However, there are 5-6 flights of stairs before you reach the apartment - something that wouldn't be ideal for elderly travelers or those with disabilities. The AC is regulated, so you don't have any access to turning it on or off and the apartment is very, very hot in June - something to be aware of. The apartment itself is spacious and comfortable, just hot.
Massimilano was a little hard to get in contact with ahead of check in - we messaged early asking if it was possible to get in early to drop off our bags but only heard back the day before, which made it challenging for us to plan our train.
Either way, we had a great time in Florence in large part to the apartment's great location. We are grateful for our time in Massimiliano's apartment and appreciate his help.
