The place is situated close to the airport but just far enough thay you don't have planes flying over your head. Nice neighbourhood. The metro station is almost literally at your doorstep, which is very convenient.
There are 2 caveats to this place.
1)Hot water is fed to the shower from a boiler which is seemingly shared with another room, so forget anything but super short showers.
2)You may be woken up by tenants turning on their shower in the adjoining room. The water flow is *really* audible.
Other than that, excellent value for the money, especially in Portugal
