Communication with Elly is great. Even before we arrived, she was there on Whats App to check when we would arrive so she could meet us and show us the apartment.
She gave us lots of tips on where to eat and where the locals go. A brilliant thing to know when you are in a city overrun with tourists.
The location of the apartment is great, within easy walking distance of the Duomo, with good restaurants on the street, and a private garden/courtyard to enjoy breakfast in.
With 2 bedrooms, both with double beds, this is great value for money.
Just be aware that staying in the city center can be noisy. The rear bedroom is the quieter one.
This would be my to-go place to stay if I visited Florence again.
