We had almost perfect stay in Paola's apartment!
Paola is a wonderful host - she always respond very quickly, she and her husband meet us in the apartment despite a late check-in and provided a lot of useful advices. They also were ready to help urgently during the whole our stay.
The apartment is very central - just in 2 minutes from the Duomo and 3-4 minutes from Piazza Signoria, San Lorenzo and palazzo Medici literally in 2 steps from the door. You can even see palazzo Medici and part of the cupola right from the window. It also large (2 bedrooms each with own bathroom), well equipped (for instance there is 3-5 different wifi routers), good planned (bedrooms very isolated and connected throw dining room) and beautiful (high ceilings, sometimes with frescos). The only minus that it could be sometimes noisy in one bedroom, but we knew it before and it wasn't a problem for us.
