We really liked this apartment which has quite large rooms and is very clean. It's a 15 minute or so walk to almost all of the main sights we wanted to see so the only buses we wound up using were nearby line 13 (going) and line 12 (coming back) to get to and from Plaza Michelangelo which gives a great overview of the entire city. Line 12 also goes to the train station. The first taxi Constanza's father called for us refused to take us to the train station because he said we had too much luggage (there were three of us and the taxi was small) but her father came down outside and made several calls until he found a taxi big enough to take everything. If he hadn't helped us we might have probably missed our train. A minor quibble is the apartment is on the third floor and the ceilings in the building are quite high so it's a bit of a climb to get to it but the people checking us in and out were quite helpful. Unlike many of the apartments we've stayed at there we couldn't find a book giving information about the neighborhood (where the bus stops are, grocery stores, etc.) but we were able to figure most things out using the Wi-Fi which worked great. The the apartment is in an old building but the plumbing was new and modern. A stack of often needed umbrellas (it rained every day while we were there) was available just outside the door. We'd definitely recommend this apartment for anyone visiting Florence.
