The studio of Sonià and Pedro was a good home to us while staying in beautiful Porto. Sonià definitely deserves the title “super host” - she is reliable to the guest she has. It was an really good service.
You are staying in the heart of Porto, which allows you to have every notable sight within 10min walking distance.
If you are keen to go out, have your night packed with constant street musicians and even better restaurants just as fall out the door then the apartment on largo São Domingos is your choice.
