Gemma is a fantastic host with a wonderful apartment. The apartment has been tastefully updated yet contains an old world charm as evident with the centuries old fresco as part of the original wall. It's centrally located with a short walk to nearly anywhere in the city center, but quiet enough for a peaceful setting. The bed was extremely comfortable.
Finally, Gemma was very accommodating to our early arrival (meeting us at the apartment so we could drop off our luggage hours before the check-in time) and was very responsive to all communication. Would highly recommend for your stay in Florence!
