We had a great 2-night stay at Giovanna's place. It was right in the middle of everything in a beautiful historic building. To be honest we didn't spend a lot of time in the apartment since there was so much to see and do in Florence, so I can't speak for all the amenities, but here goes!
Giovanna sent me a Whatsapp message about 24hrs prior which was very thoughtful of her as I had completely missed the Airbnb message (too busy wandering around Italy!). After that she was utterly charming and responsive every time I asked her a question. Lovely!
Since we were there in December and it was freezing, it was great to have such a warm heating available and heated towel racks too. The bathrooms were surprisingly modern and newly renovated, although a little cosy, but it has everything you need, plenty of warm water and good water pressure from the rain shower! We didn't find any soaps so we used our own - maybe bring your own or check with Giovanna before hand!
The bedroom was spacious and comfortable, although do note that there is a bit of noise from the street at night since it's such a populated area, and from the sound of people upstairs moving around in the morning, but we were honestly so tired from all our activities in the day that it didn't bother us! Just something to note, and Giovanna is also kind enough to point this out to you when you book her property so it shouldn't come as a surprise.
Unfortunately the washing machine wasn't working while we were there but Giovanna did offer to send us the address of a nearby laundrymat but it wasn't too urgent for us so we could do without.
There is a small elevator which fit both of us and our big luggages so access was no issue. We didn't mind walking up / down the stairs anyway - better to work up an appetite and eat more Italian food!
All in all, we had a great stay and recommend it to anyone looking for a nice place in central Florence!
