We booked about 2-3 days in advance. Alberto was very responsive by WhatsApp to make sure he knew when we would be arriving and would be there (or have someone there) to greet us.
The location is fantastic for someone making just a short trip to Florence as it is located about 5 - 10 minutes walking from the train station and is centrally located so we could walk to other areas of interest as well.
We had not intended to visit Florence and had not done research on things to do, so the overview of things to do in the city we received upon arrival was very helpful and much appreciated.
The rooms were very clean and noise from other guests was not an issue, at least during our stay.
Highly recommended for a professional and affordable experience.
