My friend and I stayed here for 3 nights, and the location of the apartment is great, everything is within easy walking distance.
The apartment itself was very clean and modern and had everything we needed. Andreia and Rui were great hosts, very quick at responding, very knowledgeable giving us tips and advice of things to do and see around the area.
They even gave us traditional delicacies for our arrival which was a really nice touch.
If we were to come to Porto again, I would absolutely stay here again.
