Maria Cristina is very dependable and offers a lot of support for all kinds of needs might show up during someone stay in Firenze (i.e. special padella for Bistecca Fiorentina).
The apartment is night combination between living a block and a house. On one side you have the feeling of the city (stairs, hall ways) and on the other side you have garden and trees.
The location could not be better as it avoids the crows of downtown Firenze, but is in walking distance from any major attraction and the bus station is 20 meters away.
