I cannot fault a thing, the apartment was lovely - it was sparkling clean, spacious, had everything we might need (condiments and even pasta were provided!), and is located in a lovely area. There is a small café and a pizzeria just across the road, with shops just around the corner, and the centre of Florence only a short walk away.
Artan and Gentiana answered any and all questions we had before our trip, and were incredibly helpful; they were very accommodating of our staggered check-in time, as not all of our party were arriving in Florence at the same time, and of our very early check-out time. We were even offered to be taken to and from the airport by minibus. We were shown around the apartment when we arrived, and had kindly been left a map of Florence, through which Gentiana talked us, and showed us the best bus routes, places to visit, etc.
I could not recommend Artan and Gentiana's apartment enough, they were so warm and welcoming, and it was such a lovely place to stay.
