As other reviews state, Luís is a great host. He met us at a very unsociable hour, as our flight ended up getting in very late, without problems! His English is impeccable too. He gave us so many recommendations of places to go, of all sorts, all on a digital map - this was so useful and it is very obvious he loves to guide tourists around his city. As we were only in Porto a few days, we only had time to visit a few restaurants etc but they were all great suggestions. His communication throughout out stay was great too. The flat was very clean, with nice bedrooms. Living area is very small but we didn't spend much time in the flat during the day anyway. Location is good too. Al in all a great value stay and one of the best airbnb host experiences I've had. You'll need to supply your own coffee pods for the machine though.
