Nadia's apartment was very modern and in a great location. The apartment is 10-15 min walking distance from all the sights. It was also a very safe location for 4 females to stay. The apartment is also very spacious and we stayed very comfortably!
The only challenge was that the heating system was tough to regulate, so the apartment was sometimes very cold or extremely hot. The wifi is also pretty poor and we were unable to get it to work. Nadia was very responsive during the weekend, but unfortunately the wifi router didn't work for us.
Overall, a wonderful stay in Florence.
