The apartment is in a great location, right next to the Santa Croce square. We really enjoyed being a <10 min walk from the duomo/city center, where everything is still accessible, but it’s a lot quieter outside without the constant rumble of people.
We were in Florence when the outside temps were 100-105 F, but the apartment was always noticeably cooler — we’d frequently swing by the apartment to cool down during the day. There’s also a nice fan in the bedroom, so for no AC it’s pretty good, although the June temperatures in Florence can still warm up the apartment considerably throughout the day.
