My friend and I were staying in Marias rental for our 4 day trip to Lisbon.
The location of the apartment is great, located in a small alley so you are just far enough from the street to not be bothered by noise, but only takes a couple of minutes to arrive in the center and explore the city.
Communication with hosts was really easy & fast, plus they are really helpful (a big plus is their ‘information package’ which includes information on the apartment and city itself, including some emergency contacts, info on transportation etc)
