We stayed as a group for one night. Mario received us and helped us in many ways with personal recommendations, booking a taxi and later checkout. We had an issue with Internet in the building and he called instantly to try to fix it. Very communicative.
The apartment is very well located and uniquely charming. AC helped in the hot day. Sofa beds were ok for one night! Area is a bit busy at night but he offered earplugs, which was a nice gesture.
