The house is just above the city centre, it is perfect to stay in to visit the city (plus it has a fantastic view on Praça Rossio).
The check in was easy and the communication fast ad accurate, the host answered quickly to every question we had.
The apartment is really clean and comfortable, if I had to say one thing the drain in the bathrooms in a little slow, but it wasn't a big deal.
Overall a really good experience, I will surely keep it in mind when I come back to Lisbon!
