I highly recommend to stay at José’s place.
The apartment is very well situated (close to the Praça do Comércio, easily accessible from the airport via the Metro, and almost everything is close enough to walk there)
The apartment is very nice, well decorated, roomy enough.
You even get a small private living room with a couch and a small table, next to the actual bedroom. Cosy and ideal for reading, or watching a movie on rainy days like we did (iPad not included ;) )
A small point of attention : the mattress is quite firm, it might be something you’d want to know depending on your taste.
About José, he’s been a great host : very nice and flexible, he gave us a warm welcome :)
Enjoy Lisboa !
