I had an amazing stay in Antonella's place.
The apartment looks exactly like on the photos: very bright, spacious, with an amazing terrace. It's located in 15-20 minutes walk from Lido Nord station (from where you can catch a train to Rome) and almost the same distance to the beach (the street will lead you drectly to spiaggia libera- free beach).
There is Pam supermarket at the next street where you can get groceries and a local market just around the corner.
WiFi is very powerful, I had no issues working remotely from the apartment during the day.
There are air conditioners in the main area and in the bedroom, which were a salvation during hot summer days. Washing machine at the terrace was also quite handy.
Would definitely stay there again!
