We had a wonderful stay in his apartment, which was a great fit for a couple on trip to Lissabon. The apartment is located on the ground floor, and is quite spacey. The apartment was neat and had everything we needed. Although there is no AC, opening up the windows gave us enough fresh air and cooled down the apartment plenty.
As the apartment is located in Bairro Alto, some noise can be expected to be heard from people heading home from the bars nearby, but as the bed room is located at the rear, this barely caused us any trouble. We slept like babies!
