Practically new apartment in the Graça area. Very clean and well maintained. Its large and has everything you need plus more. Fully equipped. Comfortable beds. Easily fits 6. Two bathrooms. The only minor issue is that we did find it hard to have both showers going at the same time with hot water.
We really enjoyed this slightly quiter area versus the craze of alto. It has a very local feeling. Lots of bakeries for breaky and restaurants neat by. Near to Alfama. It is a little further though from the major transport like trains which took about 30 min to reach walking. It is easy to catch the tram down into town or visa versa but late at night taxi or walk. Taxis are nice and cheap and it's only about 10 euros to the airport from the apartment.
Near several of the amazing view points over lisbon so don't forget to check them out.
Oh and good wifi as well.
