Stefano's appartment is huge and exactly as you see on the photos, with lovely high ceilings. It is also very central - 3 minutes walk to the Duomo, 5 to Santa Croce (which you MUST visit), less than 10 to the Uffizi, 15 to Ponte Vecchio, Palazzo Pitti and Santo Spirito on the other side of the Arno river.
Big living/dining room with frescoed ceiling, three very large bedrooms - 1 king, 1 double, one with two singles and a mini double (120 wide), a lovely big south facing terrace which in spring and summer must be wonderful to have meals on. The bathrooms are not luxurious but they do the job and with 2 bathtubs, 1 shower 4 sinks and 3 toilets, are plenty for everyone. There is a small back room with a washing machine, drying rack and iron. The central heating is very efficient and we were never cold, even in the middle of December - in any case, there are plenty of extra blankets and duvets should you need them. We noticed that rooms are also air conditioned so that would no doubt be appreciated in the hot summer months. The wifi was very efficient in all the rooms, and our hyper connected family didn't have any trouble all getting online at the same time.
The only downside is the noisy double bedroom - giving onto the lively pedestrian street, as mentioned by several people it is noisy and must be very difficult to sleep in during the busy summer months. The triple faces the front as well, but Stefano was able to add a second window, creating a sort of double glazing which dampens the sounds quite well. Our advice is to put any teenager in your party in that double room, they normally don't mind noise in the evening and sleep like the dead in the morning anyway! This is what we did and it worked perfectly :D
The other slight down is the kitchen which is in need of TLC. Like the rest of the rooms, it is big and the recent cooking range, fridge freezer, dishwasher and microwave are all vey good quality, but the cupboards and worktops are very tired. There are enough beautiful plates and glasses to feed an army but we had to hunt around all drawers to finally put together 5 mismatched knives :) This said, we did manage to cook for the family perfectly well and there are plenty of good restaurants and snack places nearby, so this shouldn't be a major issue for anyone.
This was our first Airbnb booking and overall it was an excellent experience, thanks Stefano!
