The house is newly renovated and the pictures correspond to reality. It's situated at the heart of Florence, offering easy access on foot to the Duomo and all the major sites. You can get your food supplies from the nearby Conad supermarket and cook at the almost fully equiped kitchen.
We arrived at 20.00 and a representative of Federico welcomed us and showed us the house and all the amenities. We asked for a second pair of keys, since we were 5 persons, but the answer on WhatsApp was "at the moment it's not available". In fact, they were never available during the three days of our staying. The check out was at 11.00, we asked with sms if it is possible to checkout at 14.30, but there was no answer. The cleaning lady showed up at 11.00.
Finally, if you want a vacation house, I recommend this place as a perfect choice. But, if you search a living home with personal contact with the host, I'm afraid that you have to reconsider.
