We found the apartment really good, well located and Anna, the host, and her family couldn't have been more charming. The whole place was very clean and well equipped. It is in a smart very quiet wooded residential area down a fairly long private drive.
We were invited to use any part of the host's garden and just across the drive from the apartment there is a wonderful view (with table) over a valley of olive trees and the city of Florence.
There is a comfortable and regular bus service (10 minutes walk) in to Florence (cost €1,20) which terminates in a square about 5 minutes walk from the Duomo. This works really well as driving in to Florence and/or parking is hopeless. A taxi is about €20.
We would definitely stay here again as it's good value, very conveniently located and comfortable. It is also ideal in the summer months when the city is overly crowded, hot and airless.
