The location of Silvia's place was fantastic. Walking distance to all of the historical centers, art museums, good food and shopping district. We only had one day in Florence- and even though that wasn't enough- we still felt we had an immersive Florence experience.
That being said, the apartment itself was perhaps too small for our party of four. When we arrived there was only one bed made up for us and two pillows to split between our group. The apartment is on the top floor of an older building and gets really hot during the summer days. There are fans provided to help with the heat, but it was still a little overwhelming.
If you are a couple, this place is probably perfect and spacious, and if you are visiting outside of summer, there is heating available.
