I had a good stay at Happy's place and I'd like to recommend it to you. Everything was clean and well prepared. Happy was easy to communicate with, and checked up with me frequently to check that all was fine. She helped me with tips about the city and things to do. The location is good: most "interesting" parts of the city are within 20 - 30 minutes walking distance; there are bus stops 5 minutes nearby; the subway is fairly close (Caios do Sodre), plus the commuting train to Cascais. — I would definitely stay at Happy's place again.
