Sam is an excellent host and a very interesting person. He is the perfect example why it is much more valuable to stay at a private person's place over airbnb rather than going to a hotel, you meet real people that can share their story and can give you valuable insights about the city.
The private apartment space is very cosy and is incredibly well situated in Lisbon, just a jump away from a beautiful park, viewpoint over the city and one of those charming neighbourhood squares with coffee and restaurants.
