Federico is very helpful. I planned to arrive at 7.30pm after Pisa, but I finished earlier in Pisa so I decided to go to Florence earlier and he made time to check me in. Also on the day I left, he is kind enough to let me put my luggage in the apartment and let me take the keys until afternoon.
The apartment is very near to the station and right in front of medici chapel. Very easy to find food. If you want to cook, there is a big san lorenzo market just behind the apartment. You can also eat on the 2nd floor of the markets (remember to try the gelato there, the pistacchio is amazing).
It is also true that it is noisy at night or early morning. The sounds of merchants dragging their carts on the stone street. Couldnt sleep well first night because I left the window open so I can hear them. Second night and third night, I completely close the window and it is much better. Federico also provides ear plugs if you need it to sleep.
Privacy is also very respected here. Overall, a great place. I would stay here again if I come back to Florence.
