Angelo's place is really a gem! It's a walk-up, but not considerably challenging and totally worth it when you consider the views from the windows in the apartment. Location wise, it can't be beat, you're a simple walk to the Duomo and pretty much all major spots in Florence. Check in was very quick and convenient and the hosts are incredibly responsive. While we didn't cook, the apartment was set up with a kitchen ready to cook.
Absolutely would stay again at Angelo's when in Florence.
