Cátia's place is one of the best airbnb that I've ever tried. It's collocated in a perfect position in Porto, you are close to everything by feet and also comfortable to take the metro to the airport. The house is wonderful, colorful and with a proper style. Very clean and well-finished in every single corner. The atmosphere is unique, calm and relax. Cátia is a super host, helpful and nice, she gives you city map and give some explanations and advice about life in Porto, what to see, eat and to do. I absolutely suggest Cátia's house and I hope to come back soon ;)
