Carlotta was a lovely and welcoming host and the apartment itself is authentic, charming and reflects the travel experiences of the host. The pictures online are very representative of the apartment, which is located in the historic district, only a minutes walk from Ponte Vecchio.
There are dozens of local restaurants, Gelaterias and plenty of shopping on both sides of the bridge. The local attractions, such as the palace, Santa Spirito, the Duomo, the Statute of David etc. are a very easy walk (though perhaps do this in the morning for fewer crowds or in the later afternoon when there is shade as around midday in summer is very hot.
I would recommend at least a week (at minimum 4-5 days) to enjoy this beautiful city that now holds a piece of my heart. I would not hesitate to stay here again.
The host does provide coffee, salt, sugar, oil etc and there is a shop close by if you need.
