Modestino's place is fantastic. The location is within walking distance to everything you might want in Florence, but still away from all the tourists and closer to the locals. Great food, bars and gelato nearby. The flat itself is amazing, you definitely get the feeling that you're in artist's house which makes for a holistic experience of the culture Florence has to offer. And Modestino, let's just say he's one of those hosts that doesn't merely let you stay in their flat, but truly welcomes you to their home and Florence.
It's been an absolute pleasure. Grazie mille Modestino!
