Perfect location right near the Pitti palace, great bars and restaurants and easy walk to everything. The apartment was clean and Tatiana and her husband were responsive in the communication. As other reviews state, the bathroom is really nice! Great shower and hair dryer.
A few small negative things was that the kitchen didn't have anything in the way of basic supplies like salt, pepper or coffee. So we had to go buy everything. There weren't any extra towels which would have been nice too. Also, the stove is tricky to work so remember to ask about that. Lastly, I found the bed to be uncomfortable. It was more like a double cot than a mattress. Although, it didn't bother my fiance as much so might be a personal thing.
Otherwise, amazing location, very clean, plenty of space for a studio and nice people.
