This was a great rental, and I would book again if in Lisbon. Generous with their time waiting for us to arrive for check in. Good suggestions for local food. Obviously the view is wonderful, and I spent time on the terrace both in the morning and at night. No shared walls with neighbors - in fact, I didn't see any at all on that floor over 3 days. You can hear the creaky elevator going up and down pretty regularly but it didn't bother me in the least. Although the bed was smaller than the queen I have at home, it was very comfortable - typical European futon-esque mattress, which I prefer. If you want to feel a little more like a local and not directly in the midst of the tourist zone, this is a perfect place.
