Overall enjoyed my stay in this cute modern flat with everything you need. Ricardo provided me with valuable information and recommendations - he is a great host! Area is calm and easy to get around from there to the city center and most important sightings. 2 minor things to improve: the shower has weak water pressure but perhaps this is "normal" in Porto and the bed creaks easily if you know what I mean, altough the mattress is comfy ;)
Having said that it, I can fully recommend this flat.
