The apartment is amazing and clean, and is located in a nice historical building right in the centre of Florence, close to Piazza della Signoria, Ponte Vecchio and a lot of nice restaurants and bars.
Bruno and Luca (his son) have always been very kind and quick in replying to any requests, making the whole booking and communication process fast and easy.
I would for sure pick this apartment again the next time I will visit Florence, and I am happy to recommend it: staying at a place like that is probably one of the best way to experience such a beautiful city.
