Federico was great. The check in process was a bit last second as we received the information as soon as we arrived, but it worked out. The AC worked well, and the place was quiet. The apartment is close to the Santa Croce church, we found shortcuts through that area to get to other parts of town. We had no problems getting anywhere on foot because Florence is relatively small.
There was a slight odor in the kitchen, it smelled like industrial cleaning supplies, but not a big deal because there is a door to the kitchen that can be closed. There wasn't any body wash in the bathroom, but a quick msg to Federico, and there was a brand new bottle of body wash at our doorstep the next morning!
One last thing, Federico called and scheduled a taxi for the next morning, which we greatly appreciated!
