My family of four, including kids 9 and 11, stayed here for a week and it was perfect. It's steps away from the market of the Porcellino, and a three minute walk from the Ponte Vecchio to the south, the Piazza della Repubblica to the north, and the Palazzo Vecchio to the east. It could not be more conveniently located for all the wonderful things the city has to offer.
The flat was immaculately clean, and it was QUIET! There is an Irish pub blasting music across from the entrance to the alley where the flat is located, and we were worried it would be too noisy, but we never heard a thing, either from neighbors or from the street. Also, the two AC units worked well and kept the place nice and cool, even when it was over 100 degrees F outside.
The flat itself is simple and homey, but not fancy. The two windows open onto an air shaft in the center of the building, so there's no view. But as a staging pad for rambling around Firenze, it's perfect.
The host had excellent communication and was very solicitous, even when we made things difficult by changing our arrival time repeatedly. Michaele, the on site guy, met us at the flat and let us in, and even carried our luggage up the stairs for us. He came back later to give us a larger bialetti for coffee and to drop off toilet paper and garbage bags. We felt very well cared for.
Now, the stairs...they're tall and steep. We live in DC and these are as steep as the famous Exorcist steps. There are 28 steps to climb to the flat, so it's effectively a third story walk up. It wasn't a problem for us, but just know you'll be going up and down a lot of steep stairs whenever you come or go.
Overall I would not hesitate to rent this flat or from this owner again. It's a delightful little place, clean and functional if not opulent. Go ahead and book this place with no hesitation!
