The location is great as is the pricing! It is at the top of the hill above the best downtown area so if you are visiting and want to walk around the awesome Porto downtown, this place is great! It is clean and all rooms have bathrooms en suite which is a very nice feature!
Disclaimer: we traveled to Porto with our family of 7 adults and we are tall and broad people. For us, this apartment was perfectly functional but we all felt it was small. This included standard European features like small beds, bathrooms, showers, sofa, and chairs. Just want to share that for other travelers that are built like us. But would recommend it so long as you know this!
