The apartment is located in a small street within a pretty hilly area in Lisbon, though very central, which is great. The nearest subway is pretty far, ±15 minutes on foot. You can also take tram 28 which is slightly overprised because of tourist popularity, or you can find steps everywhere.
I always am really picky about the bed, but I slept really well, it's a good and clean bed.
The apartment was equipped with almost everything you need, unless if you want to cook. I was missing clothespins to hang up the freshly washed laundry.
It's not well isolated so you can hear the side neighbours cooking, walking around and talking, which was disturbing.
All in all, I had a very pleasant stay.
