Marta's place is very homey and cozy. Definitely enjoyed my stay! Lx Factory is just a block away, very convenient.
If you are a light sleepers though, expect to hear airplanes flying above all times, people walking and make conversations or even the noises from the neighbours.
I'm not a light sleeper, so I slept well and communication with Marta and Marco were very good. Definitely be back here again for my holiday in Lisboa :)
