Great stay on a quiet street. It's mostly a residential neighborhood and away from the hustle bustle of the city center but still close to a decent amount of cafes, restaurants, and markets. Apartment was clean and just as described in the listing. There is no air conditioning, but due to the location/setup the apartment stayed nice and cool throughout the week even though it was quite hot outside.
Helena was a great host, responded very quickly to all questions and even held on to a forgotten item by one of the guests!
A couple notes for future guests: apartment is on the ground floor, so there is some street noise to be expected. Also, while Alameda station may be the most convenient as both the green and red lines pass there, it is uphill so may not be easy with folks with luggage. In this case, Areeiro or Olaias stations are better as the walk is mostly flat.
