Joao's place is practically perfect. The views are incredible, the location is fantastic and Joao and his partner are brilliant.
I loved that we were on the Riberia, but didn't have the loud noises of the bars at night. Rather the ambience of buskers across the river and of course the seagulls and boats. There are loads of stairs, but this just means you can eat more pastela de nata and work them off.
Overall this has been the best AirBnB I've ever stayed in. Although there are a few other obvisouly tourist places, this accomadation feels like you are deep inside an authentic area.
Top tip: The resturant just above the apartment, The Arc of Truth, is a gem. They do a very good breakfast and dinners.
