We were hosted by Carlos, Pedro’s dad. He was nice, responsive, and available. The communication was great, Carlos also provided us with a map of how to get to the place from the airport and he allowed us to check in before the fixed hours.
The house is good, equipped with an extra room so if you are a family it’s perfect, and the most important thing is the place is super clean! The only problem was the terrible sewage smell in the toilet, but I think that is a general issue in Lisbon. The second bad thing was the noise coming from the hosts upstairs that spoke loudly the whole night, slamming their feet on the floor, and downstairs you hear every little noise. So I suggest Pedro and Claudia invite guests to their place not to make so much noise at night.
For the rest, the place was strategic, 5 min from the center and from the Central Station Rossio where you can also take the train to Sintra. The neighborhood is quiet and safe, even if there’s a huge presence of migrants.
