My wife and I found the apartment to be very charming and clean. We were greeted by Fernando, the Property manager, on time and he made our stay very enjoyable. He was always available and willing to help. We were offered a nice bottle of red wine upon checkin.
The apartment is fully equipped as advertised and in a safe local neighbourhood. Parking is available on the street but you will have to get lucky finding a spot at times. Walking back from the downtown can be tiring after a long day of walking. But the city tram is available if you prefer.
Only issue I had was the small shower. I'm 6'2" and it was very difficult to move around.
Overall excellent stay in Lisbon for 4 nights and we would highly recommend this apartment.
