This place is great, you got everything you need for a safe and comfortable stay in the center of Lisbon.
Checking in was very smooth because the hosts were very communicative and informative.
The room is simple, tidy and had a lot of light, I would specially recommend it for a short term stay, there's multiple rooms and guests in the flat, my only negative would be that the room was not very soundproof and you can hear almost everything other guests do, but luckily I'm not very picky when it comes to that, other than this, I am happy to have stayed there and would stay again.
