The location of the apartment is quite good - close to the central station and you can walk to all sights of Florence. The check in was great, Lorenzo even let us check in earlier.
BUT, after getting used to the apartment I dicovered that the walls are wet and it looked like mold at the walls... I told it Lorenzo and he directly came back to check the situation. He said that this is no mold, that only the walls are wet... Well, he offered us to give us a full refund if we want to leave the apartment, which was very kind of him!
At the end, Lorenzo is a great host but the place is run down. You can see that the kitchen and the bathroom is quite new but the room itself is dirty (dirty walls, wet walls, etc.).
To be honest: I would not book it again!
