Great choice for Lisbon.
Antonio and his friend Jorge were so friendly and helpful, very responsive and friendly, and offering advice of things to do, see and eat.
The apartment is spacious and roomy enough for 5 adults. The terrace is the best part. We spent every evening out there, you can see the red roofs and hear the neighbours listening to Portuguese music.
Fair warning: the beds are very firm. I have a firm bed at home, but these beds were too firm for me.
Water pressure was good and the place was very clean. There is AC and laundry too.
There are a lot of stairs to climb to access the apartment, so if you have large suitcases, this might not be the place for you.
