Marias apartment is really really nice. Located on Gorriti and Scalabrini you are basically at the heart of Palermo Soho, everything is in walking distance. There are plenty of busses stopping right outside on the street, and walking distance to the metro.
The apartment is very cozy and functional, we lived two people there for 2,5 months and we really liked it. It's a small kitchen but it works, the bathroom is fresh and works very well.
The communication with Maria, and her family, was really easy and smooth, they are always there to help. And her family is super sweet.
The only bad thing about the apartment is the lack of isolation, which made it really cold during the winter. Scalabrini is also a very busy street so if you have a hard time sleeping I wouldn't recomend this apartment because you hear everything from the outside. That's really the only bad thing, everything else is perfect. But I had a really hard time with all the traffic outside.
