My wife, son (4 y/o) and I stayed at Marta's place for over a month and absolutely loved it. The apartment is spacious, clean, nicely decorated and close (i.e., walkable) to everything in Ericeira: beaches, surf spots, multiple grocery stores, restaurants, etc. And yet the apartment is also relatively quiet. We communicated with Marta and her brother during our stay and both of them were very welcoming, kind and responsive. Marta even lended us a bunch of toys for our son to play with. I highly recommend staying at Marta's apartment and wouldn't hesitate to come back.
