We had a fantastic experience staying. Alessandro met us out front and helped us up with our luggage. He gave us very clear and thorough instructions on everything we would ever need to know about the apartment and the building. He even got us to test the washing machine for him to make sure we knew what we were doing! Hah. After we were settled in, he spent at least an hour giving us tips and suggestions on what to do and where to go in Florence. His recommendations were all great. He was very helpful and accommodating. We broke a glass by accident and the next day a whole new set showed up for us.
As for the apartment, the pictures are exactly as it appears. It is located literally a stone's throw from the Duomo and the apartment balcony has an amazing view of the dome. We used the balcony a lot to start and end our days. The apartment faces an inner courtyard so there is zero noise from pedestrian/tourist traffic on the front street. Another reviewer commented on the noisy neighbors. Yes they watch the TV loudly however never in the morning nor late at night so it really isn't disruptive at all. All amenities were provided for us: full kitchen with oil, salt etc; extra towels and bedding, washing machine with detergent and drying rack, hair dryer.
We look forward to returning to Florence and staying at this apartment again! 100% would recommend!!
