We (family of four) have stayed at Ana's apartment for six nights. The location is absolutely amazing, in the center of the historical center. The tram station (for #28 and #15) is about 100 meters away, and the metro is another 100 meters walk. The Rossio train station is also very close. The building is very modern inside, and elevator was an added bonus. The apartment was exactly as described, very clean and welcoming. Very good beds, with extra pillows and blankets.
It was easy to communicate with Ana and Joao. On the day of check-in we were allowed to drop our luggage at the apartment couple of hours before the check-in time, and Ana also was able accommodated our request for a later check-out.
