I have stayed here with my boyfriend for 1 month and I would honestly recommend it to anyone who wants to visit Porto for a short or long period! It is situated in the centre, right next to the main shopping street and close to public transport. You can even see the Santo Ildefonso Church from the window. The place is clean and has EVERYTHING you might need (even for a long stay). It's perfect for 2 people. Kiki and Teresa are wonderful hosts: so friendly and accommodating :)
Thanks for everything
