Another review said this was the best airbnb they had stayed at. I have to agree. Location was good literallyby metro, supermarket very close, Porto sights nearby). The outdoor space was lovely, there were some nice treats in the fridge, guidebooks, all spaces stylish. Much nicer than home. Pedro met us in person but was not hassling me for a time of arrival (as other airbnbs have and tbh it is hard to say isn't it if you are in a new city?) and was not perturbed by our late flight which made it all the more relaxing. Also Pedro gave good tips of where to go.
Really highly recommended as is Porto itself (unless you struggle with hills/steps as there is quite a slope down to the river).
Top tip from me - z4 ticket is what you need to get here from airport
