Guido was very welcoming with us, he was waiting at the appartment when we arrived to give us the keys and he spent some time giving us great local tips, specially for food (which were great). The room and bathroom were very clean and comfortable, we had a very good rest and the shower was great. Definitely, what is best is the location, only a few blocks from the train station and about 10 blocks from the Duomo. You can visit all Florence by walking! Only point to keep in mind is that is located in a 3rd floor with no lift but this was not a problem for us. I strongly recommend this place, we had an excellent time, thanks Guido!
