Excellent location (I walked from Santa Apolónia station, and metro Terreiro do Paço is literally 1 minute away. Almost everything is within walking distance. You have to climb some stairs to get to the apartment but I guarantee the surroundings are beautiful.
Vanda was at work when I arrived but I picked up the keys at a nearby restaurant. When I arrived in my room I found a Lisbon map and a list of recommendations (restaurants etc).
I met Vanda quickly as she wasn't staying at the apartment herself but rented out her room to a friend (a nice german girl).
The only thing I thought can be improved is the bed, I think it was really hard (a plank instead of a slatted bed base).
Overall a great place to stay!
