The apartment is absolutely fantastic - it’s in an incredible location with all important sights being within 10-15min walking distance. It’s nice, clean and has good AC. Federico and Marilena were very forthcoming and provided us with some tips on where to leave our car or store our luggage, they also helped us out fast when we realized one of the AC remotes had run out of batteries.
One thing to be aware of is that the apartment is basically one huge space, meaning, that the top bedroom is not properly separated by walls etc. from the downstairs one, which means that everything can be heard. If that’s not a problem, I’d highly recommend the place and will come back myself soon!
