The place is absolutely amazing, the location is great, it's right behind Medici Palace with lots of decent restaurant surrounding. It is close to most of the tourist sites within walking distance, so living there is easy and comfortable.
The apartment itself is clean, stylish, fully-equipped and beautiful! We were totally amazed when we first walked into the apartment.
Giovanni is very helpful, nice and provide with useful information before and during the meet up. Staying at his place made our trip a better experience. I would recommend you to stay at his place!
