One word: perfect! Maria is a perfect host, always available, welcoming, and extremely nice. The apartment is great, in a charming street right in the city center. Everything you need is very close, but you cannot hear any noise from the street. We slept well, had wifi, and all of the equipment we needed and more. We had an amazing week. I absolutely advise you to stay at Maria's. I will surely stay there again if I go back to Porto. Thank you Maria!
