I was lucky to be able to stay in Florence for a month at Marzia's place. It exceeded my expectations. It's much larger than it appears in the photos and well stocked. The place was spotless. The kitchen is well equipped for cooking with a selection of spices, tea and coffee available. The little attic nook off the second bedroom is a nice place to curl up and read. There was never a problem with hot water even with 3 of us taking showers in the morning.
Marzia was always available to answer any questions that we had and has put together a little notebook with information and suggestions for the city. There are a handful of guide books in one of the bedrooms.
The 3rd week I had some friends coming to stay, and she came and gave the apartment another cleaning and changed the bedding for us. It was above and beyond what she needed to do. The welcome gifts of wine were also a very sweet touch.
Only negatives, which were already mentioned, are the 50 steps up to the apartment. This could be a problem if you have mobility issues. I got used to them quickly, and Marzia was available to help us with our luggage. The front bedroom is noisy some nights. If you are a light sleeper, bring earplugs. The rest of the apartment is very quiet.
I would not hesitate to stay here again. The location is fantastic, lots of stores and restaurants nearby, yet away from the main tourists sites and crowds. Most of the main tourist attractions are not more than a 15 minute walk away.
