Our stay in Porto was perfect because of this Airbnb! The apartment is only used for Airbnb so it is impressively clean, stylish, and has all the amenities someone exploring a new city would need. Our highlights were getting all the tips and tricks on where to go from our host right when we checked in. It was amazingly helpful to have her insight on where to dine and sights to see. They also have a small book (hand made!) to guide their guests on recommendations.
One tip from our stay is there is a rooftop bar at the hotel (Pestana Porto - Goldsmith) across the street and it was the perfect place to start an evening out.
Highly recommend!
