I have not met Marta because she was working at the hospital at the time of our arrival, but she is a nice and relaxed person and responded immediately to my text messages. Our stay at the apartment was great because the apartment is pretty big and very clean, despite a slight problem with humidity (probably due to the heavy rain for the first three days). The apartment is quite close to the metro station (a 5 minute walk), although there are slopes to walk up and down (but this is typical of the city of Lisboa). The area is quiet and residential, and only two stops away from the city centre. I would totally recommend this apartment to a friend!
