We really enjoyed our stay.
The apartment is around the corner from Ottaviano station which made it easy for us to get to after taking the train from Florence to Termini. Letizia was very welcoming to her apartment and helpful in regards to the places where we should visit. Apollo and Fragola, her two dogs welcomed us back into the apartment from our excursions and it was nice to have pets who made us feel at home.
The apartment is about a 5 min walk to the Vatican and Vatican museum and is based in a quiet area, with good transport options and places to eat out.
Definitely try out Dino and Tony (a restaurant Letizia recommended) the antipasti and pasta mixto are great value for the quality!
We were very happy with our stay and would recommend the accomodation to our friends.
