We (5 people) stayed at the apartment for 3 nights and it was great! Clean, comfortable, and perfect size for our group of friends. We didn't use the kitchen but saw it was well equipped with everything you would require. We used the washing machine which was a great help for us. The wifi was quick and very helpful for our stay as well given we were traveling from overseas with no data on our phones.
The location is less than 10min walk to SMN station which you will find the trains, many buses and taxis.
Elly was kind enough to take 30min out of her time to explain all the hot spots - restaurants, bars, and tourist attractions with maps and brochures at the house.
Lots of restaurants and shops nearby, we had the 10Euro lunch meal at the restaurant underneath the apartment and it was one of the best meals for value (starter, main and a glass of wine). Thanks again Elly! If we come back to florence we will definite stay here again.
