My time here was pretty pleasant. I wished I could had stayed way longer. The host is enchanting, caring and nice. The accomodation has everything you would need and the location is very convenient. Apparently, the fact that there is no lift is something usual in the city, so don't let that to be a determining factor when choosing an accomodation in Lisbon.
There is free parking in the area, groceries stores and a bus stop right in front of the building.
Thanks for everything Alex and Victor!
