I had a pleasant stay at Flávio’s place, which is as shown in the photos.
Didn’t meet Flávio during my stay, but he was very helpful, friendly and quick to respond via messages. The person who met me for check in was also friendly.
One thing to keep in mind - this area of Lisbon is right in the middle of a flight path from the nearby airport. So if you are a light sleeper, I would recommend bringing some earplugs
