The apartment is perfectly located, we did everything by foot. The wifi did not work during the last two days but it was probably just our luck. Even though we didn't see him, Matteo was of a great help at any issues. We had a late check-in due to our plane arrival time but the housekeeper lives upstairs so it was very convenient for that! To conclude, we had a lovely stay in Naples and I would recommend this apartment!
Grazie Matteo e Teresa!
