The place is very large and well-fitted. Two lovely balconies, a washing machine, a full kitchen, two bathrooms, all very clean. Antonio was a lovely host, he even picked me up from the airport and told me all about Porto before dropping me at the Airbnb.
The location is perfect, about a 15 minute walk from the start of the historic center, literally 1 minute from a metro station that will take you to the airport or the train station, but still in a very quiet area. Highly recommend.
