This apartment is fairly conveniently located in Campo de Ourique, near the Rato metro station. My father-in-law stayed here while visiting us in Lisbon, and it was perfect for a short stay for one person (a couple could easily fit here, too). The apartment had everything necessary, the only smaller downside was the living room having no windows as it's in the middle of the apartment between the bedroom and the kitchen. The street is quiet, but like most Lisbon buildings, you can easily hear your neighbors. Self check in and checkout were super smooth. All in all, I can recommend the apartment!
