What a wonderful stay in a great area. The apartment was super for two of us very clean and uncluttered with comfortable double beds, great bathroom and kitchen and the living room was a fantastic place to put our feet up and have a glass of wine after a long day of walking and site seeing. We felt very safe here at all times of the day. Uber was quite cheap when we used it and the metro isn't too far (steep climb up and down the hills).
A couple of things to note:
1) When getting an Uber, walk to the end of the street by Allfama restaurant and get it from there. You won't need to walk up or downhill then. There is a barrier at the end of the street, so that's easiest for pickup.
2) There are two flights of steep stairs which will be difficult for people with mobility issues.
3) Plenty of restaurants within a close walk - we enjoyed the pizza shop down the hill and the Fado music and dinner at Arcaz Velho at the end of the street. Yummy sangria on the same side of the street as the apartment where the board says 'happy hour'.
We highly reccommend staying here as it's a great area and easy enough to get to other areas of Lisbon from here.
