Catarina welcomed us warmly and spent a few time describing herself and explaining us the essential about our stay in Porto, she shared some of her favorite address to eat or to hang out and was absolutely available during our stay for any problems. The room is comfortable and the entire appartement was perfectly cleaned before our arrival. Just be prepared to walk a little before arriving to the very centre of the city, otherwise the metro is 5 minutes far from the appartement and is not expensive. I recommend staying at their place!
