Ana's apartment is not large, but very comfortable for one or two adults. It was clean and well-appointed. The bed is extremely comfortable. I didn't check, but it felt like a Tempur-Pedic mattress.
The location is wonderful. The apartment is on a very quiet side street, and on the other side of the block there is a very busy street full of many nice options for food/drinks/nightlife.
As a host, Ana was one of the best I've had in years of staying in AirBNB's. My wife became ill during our trip, which we thought might require us to stay beyond our checkout date. Ana was very proactive, sending me links to the nearest available AirBNB's, and also links to the nearest medical facilities.
I strongly recommend Ana's apartment, and plan to return to it when I am back in Lisbon
