I stayed for 3 nights at Rita, Tiago and Isabel's place and had an amazing time in Porto. The room was lovely, bright and neat, Isabel even picked me up from the metro stop with the car which was unexpectedly lovely of her. She gave me all the information about the public transport and places to see, food and wine to try and made me feel very welcome as a guest. I also really enjoyed the coffee and fresh breakfast rolls with her homemade jam in the mornings (all the reviews gushing about that were spot on!). If you prefer staying in a quieter area of Porto yet still a reasonable 30 min bus ride from the centre (and 10 min bus ride/20 min walk from the Matosinhos beach and those incredible grilled fish restaurants), this is THE place to book. Can't recommend enough.
