I highly recommend staying at Lourdes's. My friend and I really felt welcome and at home at Lourdes and her husband's. The room was really nice and clean with a nice view on the garden. The house and garden are absolutely gorgeous. We enjoyed the whole experience as we were able to chat with both of them. Her husband was really helpful on suggesting some interesting itineraries. We also had some great talks about Portugal... It definitely enhanced our experience of Porto. Thank you Lurdes and Adérito :-)
