We were staying at Patricia's place to visit for the first time Lisbon. The location is great since the place is really near to famous neighborhoods like Alfama (15 mit by foot) or the Cementery with nice coffees and parks around (10mit). At the same time we were living among locals with nice and not expensive restaurants and many small business. The apartment is tiny but for us was enough to enjoy 4 full days at Lisboa where we were mostly out, but we enjoyed to have nice easy breakfast at home with a nice view.
Nevertheless I will check depends on your high if the place feets your size since the roof is slop and could be not nice for big persons.
We didn't get to met Patricia but the communication was really good and we were really happy to have some tips written from her to go to some not super touristic places in Lisbon, we followed a couple of them and they were great.
