I really enjoyed my stay. Mario is a very kind and polite host who did everything to make my stay as comfortable as possible. First, the room was still occupied when I arrived but Mario gave me a greater and more luxurious apartment in the same house for the weekend. Everything was clean, the kitchen was really good equipped with everything one would need (including coffee and chocolate - thanks for that). The location of the apartment is amazing! You can walk to all the points of interest and the Jardins do Palacio de Cristal are in the neighbourhood. Next time when I go to Porto I will contact Mario again - the place is just very nice. Thanks again! I had a wonderful weekend
