The stay was pretty great! The apartment is big with a great kitchen area. The kitchen is well furnished with a lot of pots, fry pans and other utensils. There is also stuff for the breakfast (cereals, coffee, some cake, tea, orange juice ...) which was appreciated.
It's also close to the train station with direct trains to Florence S.M.N. That station is on the way to a lot of destination so we didn't even had to go to the main station to go to Sienna for example.
The only thing I was a bit disappointed in is the quality of the mattresses. They aren't old or anything, they just seemed a bit cheap.
Anyway, I was pleased with the stay! A very convenient place, both for the location and the size of the apartment.
