We really enjoyed our stay- the apartment is just like the pictures and has everything you could need. Location was good for us as we walked to the main tourist sites from the apartment. We found the apartment easily as we got off the airport bus at Beverello and it was about a 15 min walk. The map app takes you slightly the wrong way as an elevator/ steps are closed off due to building work, but we walked a bit further and took the next set of steps.
There are lots of places to eat close by, including a couple of very good gelateria. Casa Infanta ) was one. Apartment was very clean and Gianlucar was very quick to respond to messages and provided recommendations for places to eat.
