The Apartment from Lorenzo is really near to the central station and by side that the house numbers are not in order easy to find.
The area around the apartment is quite nice, you can reach the city center by a 15 minute walk.
The Apartment was really nice and comfortable.
We cooked our own meals and used the house-coffee-maker. This was a great experience!
The bathroom is totally new and nice!

Also we get a map and Lorenzo also sight were I can find a vegan restaurant (because I ask him) thanks for the tip!

Anyway, if you want to stay in Florence go to Lorenzo! Totally recommend it.
