Luis and Ines have a fantastic apartment. It's a delightful space and in a great location (super close to lots of tourist sites). Our hosts made sure we had everything we needed to make our stay wonderful. Luis and Ines are the best Airbnb hosts we've ever had. They are incredibly fast at responding to messages, are kind hearted, genuine and sincerely wanted to make sure we had a great stay in Porto (which we did). They connected us with a great tour company who gave a fantastic tour of the city and also transported us from the train station to the apartment.
I would, without reservation, stay at Luis and Ines apartment again. We felt completely taken care of, from the time we booked the reservation until the moment we boarded our train to leave. Porto hold a special place in our hearts due in part of our fantastic hosts.
The only recommendation I would make, for those who are sensitive to noise, is to bring earplugs. The streets are made of cobblestone and cars driving up and down the street can make a fair amount of noise (especially on the weekend when more people are out and about).
