We had a lovely week-long stay in Sonia's apartment. Her husband facilitated an easy check-in and gave us some helpful recommendations. We loved the high ceilings and great light in the space, and there is a beautiful view of the Clerigos tower. The location is perfectly central. We walked everywhere. Light sleepers should be aware that the square is lively, with music stopping at 2215 (10:15p) or so each night. Some street noise continues after that, because the square is home to multiple popular restaurants. All day there is construction going on nearby, but that seems inescapable in Porto, currently. We enjoyed being in the middle of it all.
