The location is good. Walk 6 mins from S.M Novella. It is also very convenient to visit all tourist areas on foot. We didn't take any public transportation. There are so many good restaurants around there.
Elena is a very good person. She introduced the best things of Florence to us, especially the restaurants.
The apartment is near to the rubbish recycle point and a busy road. The collection time is at the mid night. Meanwhile, there will have many motorcycles passing the road at early morning. Therefore, if you come back after mid night and wake up before early morning. It won't affect at all.
