Joao (Sandra's husband) kindly waited for us while our flight was heavily delayed, and greeted us warmly in the apartment. He explained everything very clearly and gave some useful local suggestions! They both responded quickly to our queries during the week as well. The apartment is lovely, a fully equipped kitchen and even with every coffee making option imaginable! The area was very quiet, and walking distance to several main train stations (Cais do sodré and Rossio) and the centre of Lisbon. Couldn't recommend it enough!
