Joao's place was nice enough.
It is a simple bedroom in a big flat with other people renting a room and sharing a bathroom. In other words it feels like a small hostel, which I guess was what I did not expect. Our bedroom was a bit noisy from the street and from the airport.
Nonetheless, well located, within 10 min to the metro and 5 min taxi drive to the airport.
Good to stay for a short stay if you need to be nearby the airport.
