We stayed for 2 nights.
Both Franco and his wife were very welcoming, gave us lots of info about the area, restaurants etc. Flat was lovely (albeit smaller than it looks in the photos) and full of character. Great kitchenette where you can cook if you want to. Bed very comfortable, bathroom and shower great.
Tea and Nespresso machine provided but no milk so I didn't use it (hubbie did, but I can't stomach black tea or coffee).
Location is perfect, and building is quiet.
Taxis go down the street, and the metro is close.
Including the rather expensive cleaning fee of $50 it was almost $200 (AUD) per night which is a bit high.
Be aware of 3 flights of narrow steep steps to get to flat.
