We had a fantastic stay in Lisbon in the apartment. I think this is the best one I have stayed in on Airbnb. The apartment is very nicely laid out with a tucked away area for the bedroom and a nice open plan kitchen and living room. The balcony is a nice touch where you can catch a glance of the river down below.
It's really near some nice areas of town (it is a bit Hilly though) and it a great place to explore from.
Joao wasn't there when we stayed but Sinara was there to welcome us and was very helpful throughout the trip. I would recommend!
