Marco and Carla were wonderful hosts. Marco gave us excellent walking directions from the train station to their apt. Carla met us upon arrival. Very friendly, she offered helpful tips for navigating Porto and choosing restaurants. When it was time to leave, she also kindly ordered a taxi for us. Their apartment was very clean and spacious. Decor lovely, especially the bedrooms with the lighted stonewalls and floor to ceiling windows-- offering partial view of the river. There were 4 of us (two couples), so plenty of room!! Location was quiet cobblestone street residential area, within walking distance to river, shops and eateries. Highly recommend!!
