I can only confirm the previous comments!
The flat is really nice, really cosy! You literally feel at home. The neighborhood is great, close to the harbor and a few minutes on foot from the main historical sites. Moreover the flat is well-furnished : good wifi, cleaning supplies, breakfast goods, towels, all you need!
Concerning Enrico and Fira, they are adorable and very helpful! Enrico allowed us to use the flat a few hours more than the check out hour. Don't hesitate to ask them anything they are never short of good advice!
