Amazing place! Ada's apartment was perfect for our stay in Florence; it was spacious, beautifully decorated, not to mention the amazing rooftop terrace. The view is absolutely breathtaking from the terrace and Ada has put a large umbrella to shade you from the sun which was perfect as it was super warm in Florence when we were there.
The apartment is close to everything you need- public transport, the main train station, restaurants and a supermarket.
The air conditioning was also a great bonus after our days exploring Florence on foot. Another lovely bonus was the cold juice and biscotti on arrival- it was a nice touch!
The only cons of the apartment, (which are hardly cons at all) are the massive flight of stairs and that there's no wifi in the actual apartment which I thought there would be. However, the stairs were good exercise and there's free wifi on the street downstairs and in most cafes so we didn't find it problematic.
Would definitely recommend the apartment.
