The apartment was great, it was very clean and comfy, and it was just like advertised in the pictures shown here! Also, Ulrika was very helpful and nice, she gave us good suggestions of places to visit, eat, information on transports to and from the apartment, etc. In our case, we preferred to walk until the historic center to see the city. It is a nice and easy walk until the center, but you can also go by bus, so you have both possibilities. The check-in was great and very easy.
Overall, great apartment to stay if you want to visit Florence!
