The apartment was a lovely large space for my fiancé and I over a week in in Florence. The location was perfect, so close to the Duomo and other sights as well as Eataly and great shopping. There are 3 flights of stairs up to the apartment but our host was nice enough to help us with suitcases, this was tolerable day-to-day without luggage. The rooms are well proportioned and very clean. It was also nice having a seperate kitchen diner from the sizeable lounge.
The downfall was that the hot water only lasts for a single shower so you will need to schedule turns if there are a couple of people staying. Also no jug for boiling water when we arrived but the host said they would remedy this
