The flat is nice, well equipped and very close to the main touristic attractions (Santa Lucia, Piazza del Plebiscito, the port to take the boat to Capri or Ischia, etc. But a bit far away from the central station : circa 40 minutes by bus).
We were warmly welcomed and although Rosaria does not speak english, the communication was good.
The only thing to note is that the flat is not well insulated (when the windows are closed you can almost feel the air from outside) : in March the nights are still cold and we both caught a cold!
Great stay though, in a beautiful city : we recommend this flat.
