Nice apartment in really perfect place, just opposite of the museum of fado with a lot of small, climatic restaurants around. Walking distance to every interesting piece of Lisbon. Helpful owners, check in / out - no issues.
We’ve got a surprising bonus as there was a fado festival during the weekend of our stay so we could enjoy concerts on the nearby scene for free :) So check if sth like that is planned during your stay and decide whether you like fado music till the midnight two days in a row (we really enjoyed it).
