Elena and Oliver were kind enough to arrange an earlier Check in time for us. Their friend Federico met us at the place, let us in and explained how everything worked in the apartment. He was also very helpful with providing recommendations for places to eat and see.
The place was very comfortable, the air conditioning worked well which is important if you are going in the summer! There was also a bottle of wine waiting for us on arrival. The location was perfect. In general you don't need a car or taxi in Florence everything is walking distance!
We had a very positive experience.
