Stayed there to attend Websummit and the location was ideal and had a great view. If you want to see Lisbon, the city, the location might be a bit far.
Biggest issue was that my friend who stayed at the big bed ended up getting bitten by a bug for 2 nights. It stopped when he moved to the couch on the living room. I suspect bed bugs but I didn’t check the bedding, so can’t tell for sure.
Bathroom was clean. Amenities are ok. Good, fully equipped kitchen.
