Isabel and Rogério are great hosts. Rogério was kind enough to dispose of the garbage we left since we had to rush to the train and had forgotten to check where to throw it. He also gave us a great introduction to the surrounding neighbourhood from the terrace.
Before I checked in I did not understand it was a rooftop apartment, which was a pleasant surprise due to the amazing view of Rossio and the surrounding hills with São Jorge castle. It also meant there was a lot of stairs to climb (no elevator) and very low ceiling, but it was not really a problem.
The place is well worth the price.
