The apartment is exactly as listed, the pictures are a good representation. It is quite small, but that is to be expected in Lisbon. The location is ok, it is round the back of the castle and slightly removed from the main city centre. Also, it is at the top of a steep hill, would definitely recommend catching the tram from the metro station.
Could not fault Mariana. She was so welcoming and friendly, and also extremely helpful explaining about the apartment and check out. Also, before we got to Portugal she sent through really detailed travel guides. Definitely a 5 star service!
