This is a great apartment. Two floors both with nice sized balconies with views to die for. Modern furnishings in an apartment fit out for the traveler. Plenty of room and keyless access so no need to coordinate the pickup or drop off of a key. (An easy to remember number is given to open the door which is set up by the cleaning service.) Multiple air conditioning units and they all work well. Well lit, modern appliances (including washing machine conveniently on the balcony by the clothes lines, complete with clothes pins). Very quiet in the apartment and even on the balcony (even when the neighborhood was somewhat noisy!).
One caution. This apartment is not handicap accessible (or anything close to it)! It is on the second floor (which we Americans would call the third floor), plus the master bedroom and bath is another flight of stairs above it. Add to that it is on one of those very steep Lisbon Streets that is primarily steps and not road (indeed you will be given an address of a building at the top of these steps and then have to carry your bags down to the front entrance (and then of course up the 2 or 3 flights to your bedroom)). That is Lisbon. It is all worth it, but if you have trouble with stairs, this apartment (and probably Lisbon) is not for you!
