This place is one of the cutest air Bnbs I’ve stayed in. The patio was great and quiet. Walking into the building you would think the street noise would be loud but this faced inside a courtyard so you couldn’t hear any noise at all. Everything worked well, A/C, shower, tv. There were power converters already there.
The best part is the location. You are a 5 minute walk to so many great bars, restaurants, and historic sites. Walking to the port was only 25 minutes. Definitely recommend this if you want to be in the heart of Porto but still want a well maintained, secured, and quiet place to stay.
