We really enjoyed our stay in Firenze! We didn't meet Marella but she gave us very good advices about the city and she even booked a nice restaurant for us! (Many thanks again !). It was very nice because she was flexible about check in and check out times. We were very well welcomed by her mother. Last but not least the apartment is so lovely and clean (exactly as on the pictures) and very well located, very close by feet from all the monuments! Even if it was very hot when we were in Firenze we didn't suffer from it in Marella's appartment because there was a fan, so good idea :-). Another good point for people (like me) who like sleeping when it's totally dark, it's ok !! ;-)
We definitely recommend Martha's appartment and will go there again if we go back to Firenze!
