I stayed at Marta's place for one night on my way from Lisbon to Porto (did not want to stay in Lisbon). The room is convenient but also a bit noisy (airplanes). It woke me up a bit earlier than expected but I am a very light sleeper so this should not be a problem for most people. Communication with Marta was fine. She seems to be a nice person although I have not met her in real life (her mom gave me the key) It is a great place to stay for long distance travellers. Great value for money.
