We had a perfect 5 nights stay! It is located in a very convenient neighborhood, 5-7 minute walk to metro, walkable everywhere, and there are so many nice restaurants/bars just a few minutes by foot. The flat is clean, well decorated as you can see in pictures and worked very well for two friends traveling together. I slept on the sofa bed, which was super comfortable that I forgot I was on a sofa bed :)
During our stay, André was super helpful and made us feel at home. Highly recommend for anyone visiting Porto to stay here!
