My family of four had a great stay in Vins' apartment. The check-in experience was wonderful, with Vins and his brother Giancarlo waiting for us at a corner (as the apartment numbers are quite confusing for taxis to find) before bringing us all the way into their apartment for a short briefing. The apt is tastefully done and very clean -- it felt like we stayed at a hotel suite! And the location is very central to all the sights and shopping. Check out was also hassle free, and Vins even helped us keep our luggage until it was time to board our train. When we come back to Florence, I hope Vins apt is available!
