I rent a bedroom with double bed in apartment at 4th floor located in Novoli area. It's far 18 minutes from the center, 12 minutes from the airport and 15 minutes from Hospital Careggi by car.
You can also go to have a walk in Cascine park that is far 15 minutes by walk.
There are a lot of bus stops both in Via di Novoli and in Via Baracca and are all very close to my apartment (50 to 100 meters).
You can also find a lot of car sharing and bike sharing services like enjoy, car2go, mobike.
