First, I would say Lurdes is very prompt in responding to your messages. With that in mind, I really enjoyed staying at their place. One has wifi, and one's own bathroom. The room is on the top floor and the windows open up to the street. It is very neat and clean. The best part of it is the house itself is a throwback to the olden times. Wooden floors, wooden stair cases, there were beaming in the room I stayed in. It were as if you can imagine the family living and growing up here. Kids going up and down the grand staircase, or imagining life as you stayed in the room- perhaps the family gathering to play in the room. It makes you imagine living in Porto- not just visiting.
It is not far away from the center of Porto. It took 15 minutes to the train Sao Bento station. (And that includes taking pictures and checking out the Church of the Holy Trinity and the Municipal Hall which is on the way) It is far away enough from all the tourists and the crowds, so one really feels like living in the city, but near enough to walk to the tourist sites and the old town.
Adelito welcomed me in. And he will have a lot of suggestions for your visit. I stayed 2 nights and I hope in the future to stay longer as day trips to Braga and Guimaraes which he recommended sounded so interesting! He is very helpful in giving suggestions. The bakery around the corner down the street is a fantastic suggestion both into local life and a place to get breakfast.
But I think the best part still is the home itself. The moment you step in, you know this is a place with a lot of history and stories. It will be tempting not to leave the room and just enjoy the space.
