The view was amazing, loved waking up to that view each morning. The location was fairly central and we were able to walk to most locations. We were met at the apartment for an easy checkin. The only challenge we had was actually getting to the apartment. There are road barriers that prevent cabs or ubers from being able to drive to the actual apartment (local traffic seem to have some sort of pass to enter through the barriers) so you need to walk steps or a hill to get to the apartment. This wasn't an issue if we were just out sightseeing (Lisbon is mostly hills) but when we arrived jet lagged and dragging big suitcases up the hill we struggled and we are young and fit. If my parents would have been with us they could have never managed it so just beware.
