I had a wonderful experience staying with Cristiana and Marco. Their flat is cozy with lots of thoughtful touches - and I am also a big fan of their cat, Micromilla. The apartment was in easy walking distance to all of the main attractions, and also just a few minutes to the train station. Cristiana gave me so many local tips for food and shopping; if you want to get off the beaten path, so she is happy to help. Breakfasts were pleasant and I really appreciated their willingness to chat with me in Italian and help me practice. Also, don't let the lack of AC put you off; I was worried about this, because it was quite hot in Florence when I visited, but the room was quite comfortable when I opened the window and turned on the ceiling fan. I'll definitely stay there again on my next visit to Florence.
