This flat is in an outstanding location, and for my money that's what you want it for: casual walking distance from some of Lisbon's most beautiful streets and lookout points, a kitchen with enough crockery to pull a meal together if you're done with sardines, and a comfy bed.
The only thing missing was a sofa or an armchair for relaxing when you've had enough of exploration for one day. I maybe should have looked more closely at the photos before booking, but I truly can't complain after a great few nights in an amazing part of town.
