Wonderful apartment by the Ascensor da Bica in the Bairro Alto region of Lisbon. Easy walk over to Chaido or down to Cais do Sodre. My personal favorite was heading down to the Time Out Market for dinner.
This area is lively into the night, but the new, modern windows do a great job blocking out the sound if you tend to crash earlier than the locals.
João was great -- when I arrived he helped me track down something that I had forgotten to pack. I would not hesitate to stay here again.
