Being a solo traveler as a woman, I must say I did not feel safe or comfortable in this area.
The communication from the host was good and the apartment is what you can see on the pictures. However, compared to other apartments in lisbon in better areas, I feel like it’s overpriced.
Something that I read in the comments and I can confirm as well: the smell is really really bad and the walls are extremely thin. When I stayed there, I had really loud neighbors up until the middle of the night.
Working from home, the wifi was perfect and I had never any issues. Also the kitchen has all necessities.
I also forgot something when I checked out (nothing $$ valuable, but a personal value to me) and the host immediately asked the cleaning staff, but it seems like they just took it, since I never heard back..
