Excellent place to explore Florence, 5 min to Duomo and 10 min to Uffizi. The roof is AWESOME, outstanding view on Duomo and the city - even better than pictured. There are tables to have dinner or a glass of wine in the evening and enjoy the view.
All listed amenities work, A/C works in all rooms, good kitchen. Sid is a great host. Nothing to complain really. Yes you need to climb 90 stairs - but this is a good practice to climb the Duomo.
