We enjoyed our stay in Marco's Florence apartment. The apartment was very clean, comfortable, and well appointed. Our family of four (two adults and two teens) had plenty of room. Marco was a great host and was always available to answer questions quickly and provide tips and advice.
The apartment is fairly conveniently located, a few blocks further away than I would choose again from the main areas we wanted to see but close by to some other spots. But it was definitely walkable to all the spots we wanted to visit in Florence.
Overall we had a great stay in Florence, this was a great apartment for a family, and Marco was a great host.
