I stayed in Guido's appartement for 4 weeks and it was wonderful! Everything is as in the pictures, it was clean and wel equipped with everything you need. Internet works well, very fast and without any problems.
The location is unbeatable, just around the corner of Ponte Vecchio in a quite street, with everything in walking distance.
Guido is a great host, very kind and very responsive if I needed anything.
I would recommend this appartement to everyone visiting Florence!
