Giovanni's place is very good if you want to be close to all attractions. It is right in the middle of everything and short walk to all attractions. Giovanni was very helpful ordering Taxi from and to the airport and explaining directions etc.
Apartment is clean and everything you need is available. It is more suited for younger people and if you want to stay up late because streets can become noisy so no chance of sleep if you want to go to bed and get up early to see attractions.
