Maria is wonderful host, one of the best I've had if not the BEST! She made me feel at home from the moment I walked in. I really enjoyed talking to her and appreciated the effort she made to speak Portuguese slowly so I could practice some of my basic Portuguese skills.
The room is spacious, comfortable and spotless clean. Yes there are rules to follow in the house but they are simple, very clear from the beginning and they allow to keep the spaces clean. The appartment is very close to bus stops, metro stations and the sete rios bus station. If you are feeling adventurous you can even reach the city centre by foot it's about an hour but a very easy walk, it's all downhill and you get to explore along the way.
I really enjoyed staying with Maria and will definitely stay here on my next visit to Lisbon!
