Our family of 5 stayed at the apartment in late July 2019 for 3 nights as we used it as our base to tour Florence and Tuscany. The location was great --- 5 minute walk from the train station and 15 minutes from all major Florence attractions. We felt safe walking at night and there are many restaurants within walking distance.
The apartment itself was very good --- lots of space, very clean, air conditioned, bathroom was nice, full functioning kitchen and great terrace to sit and enjoy the views.
The host was very responsive and helpful and made the check-in and check-out process very easy for us.
The only thing that was not optimal was that the building is very commercial and the halls were often dark at night. Also --- the building has an elevator (which is good), but it is quite small.
I would definitely recommend this place to a family travelling to Florence/Tuscany --- very comfortable with many great benefits
