STAY HERE!
My fiancé and I stayed here for 7 nights and we loved it. The house is a converted covenant and is huge! If you want somewhere that is very florentine, where you can immerse yourself into the florentine culture (something you would not get in a hotel) - then book Raffaella's place!
For the 2 of us we were spoilt for room really, the bedroom was spacious and opened out onto the shared garden (good for hot evenings) and then led on to a walk-in wardrobe! The bathroom was modern and clean and there was shampoo and Italian soap and toothpaste for us to use - nice touch and very useful as we didn't bring any as we flew with only hand luggage!! There is also a second toilet and I think the couch pulls out into a bed? The open plan lounge and dining area is huge and is lovely if you want to eat in - we ate in one night and were able to set the table etc :)
Finally - which the fellow Brits and Americans will be keen to know - the bedroom has a large TV... Now the actual TV is full of Italian speaking channels HOWEVER it is a smart TV and so you are able to log in to your Netflix account :) we spent the majority of our time out in Florence however when we were in, we were able to watch our shows etc on Netflix!
Most importantly, Raffaella and her daughter Silvia are really really lovely, exceptionally approachable and live next door so were right there if we needed them. Raffaella was also a very good little guide for us and frequently recommended amazing places to eat and visit in Florence such as the Cucineria la mattonaia restaurant, the antique market in piazza santo spirito, and the walk up to the church of San miniato. We loved our trip to Florence and will definitely be back - we would definitely stay in Raffaella's place again too! :)
