Isa contacted me from the beginning to send me the instructions to get to her place. It is very well located, a 3-min walk from the metro station and it has a bus stop almost in front. Isa suggested some restaurants of typical Portuguese food, some places to visit, and how to get there. She was at all times very friendly. Her place is big with three rooms for guests. Everybody was respectful. I would have loved to stay longer in Porto because it's a beautiful city, and definitely I am going to come back to stay with Isa. 100% recommended.
