We stayed 3 nights with a family of 4. The apartment was great. Newly renovated, well equipped with all needed (incl Nespresso cafe machine). The location is just perfect, everything is in walking distance (5 min to the Aquarium, the old city or public transport) and 15 min to the train station for Cinque Terre. Very quiet and nice neighborhood with shops and restaurants. On top our host, Andrea was very welcoming, helpful and very accommodating.
I have nothing else to say that I truly recommend this place for a stay in Genoa.
