Maria's apartment is located in the very core of lisbon, making it a perfect starting point to visit the whole city. The street where it is located is overall quite silent, and the windows decently isolate the flat from the outside. In general, it is clean and quite cozy. However, the price appeared to us too high for the actual quality of the apartment. The flat is really tiny, with a really small bathroom and basically no space to sit, hang out or chill. Moreover, the walls are extremely thin, so much that you literally hear neighbor's conversations. It gets really annoying at night when you try to fall asleep and you can't because of noises coming feom neighboring flats.
In general, we found it a bit overpriced, but eventually a good place to stay thanks to the amazing position.
