Maria was very kind and often asked if there was something she could do to make it more comfortable. The room was nice and bright and had a great view over the Nossa Senhora do Monte. The house was cleaned on a daily basis, including the showers and kitchen and even the bin in my room.
After staying for two weeks in the room/house, I doubt there could have been a more ideal location in Lisbon for me. It is in a quiet area at a walking distance from the city's big squares (<10min).
