We've stayed at Rosana's place for a month. Everything was perfect starting from the check-in all the way until to the check-out.
We were met at the airport by Rosana's husband Gennaro, who took us to the apartment in his car. He even showed us some nice pizza places on the way (spoiler alert: they were awesome).
The apartment is exactly as described, with a well equipped kitchen (everything you you'll ever need even for a long stay), super fast internet connection (up to 100Mbps!) and a great location near to supermarkets, the train/metro station and within walking distance to the sea, with mountain and city views.
Rosana replies to messages so fast that it seems like she constantly has the chat window open :)
All in all, I highly recommend staying at Rosana's place, especially for longer trips.
