Michele's place is clean, right in the city center of old Florence, and close to many sights and shopping and good restaurants and gelaterias. We went during the tourist off-season, so it was very quiet, though I would imagine during the high season it could be loud, but we had no problems with noise. The apartment is SO spacious - we had 10 people (two families) in the apartment, and there was plenty of space for everyone!
Keep in mind that the unit is on the 5th floor and there is no elevator, but it's better to be higher up so you are away from the noise! There's a little roof deck so you can overlook the city and the quiet.
The BEST part of staying at Michele's place was a private customized cooking class run by a chef (also named Michele). He took us to a local market where we had cappuccinos, bought all of our groceries and explained the ingredients we were shopping for, and then showed us how to make several easy yet delicious dishes - all with 3 wines to pair with the meal. It was a WONDERFUL experience (also convenient because we didn't have to travel to another place, and it was a private class) and I recommend it to everyone who stays at Michele's place. It is one of our best memories of our entire Florence stay. Thank you again!!
