I stayed in Casa 22 for two weeks during July and was very pleased with my choice. The apartment, although very compact, is thoughtfully and efficiently laid out. Handover of keys and sharing of local knowledge was smooth. The view to Santo Ildefonso church and Praça da Batalha is wonderful and provides an ever-changing scene of activity. The noise levels can be quite high at times but this is more than compensated by the centrality of the location and convenience of the apartment. I can thoroughly recommend Casa 22 for a single person or couple seeking a genuine slice of Porto life.
