I had fantastic stay at Elsa & Rubina's place. It is in a convenient location next to Sao Bento train station and very close to other sites including Livraria Lello, Clerigos Tower and Porto Cathedral. Elsa and Rubina were very accommodating. I had an early evening train leaving Porto and they allowed me to store my bags in a separate room in the building. I highly recommend Elsa and Rubina's place. They were excellent hosts!
