We spent a week in Lisboa and the location of the apartment couldn’t be better. It was close to all the areas you want to see in Lisboa.
The communication with the host was good, we had to call them to get the wifi password but they responded immediately.
At night you can hear people walking and talking on the stairs so it can be a little bit annoying if you aren’t a heavy sleeper.
No elevator and the stairs feel small at the beginning but you will get use to it.
