Nuno is great fun. My first night in Lisbon my friend was delayed so Nuno took me for a drink and then showed me a local restaurant with some great dishes. We ended up having a hugely entertaining evening and he gave me a load of tips on local cuisine and how to get to the beach. The airbnb is small but he is very honest about that and would not be good for anyone with mobility issues to climb the metal ladder into the "loft" bedroom. However, I really liked the location, 10 mins walk from Rato Metro and 15 mins to reach the down town squares and Bario Alto and it is very tucked away so you feel you are seeing a tiny bit of Lisbon that you otherwise wouldn't guess was there.
