We stayed at Maria Rosaria for 2 nights with 3 people.
Maria Rosaria was very helpful in terms of flexibility on check in hours and tips for things to do around the city
The apartment is fantastic and perfectly located with a beautiful terrace.
Only negative points were the AC in the living room, which was not working, and the fact that only 2 bedrooms and 1 bathroom were actually available instead of 3 and 2 as described in the apartment listing. It would have been nice to have access to the second bathroom especially because to have access to the main bathroom you have to go through one of the room.
Overall the apartment is great and I would recommend it to anyone for future staying.
