To call Nuno&Anita "superhosts" would be an understatement. We have rarely, if ever, met hosts who so diligently and pleasantly prepared and cared for their guests.
The apartment is amazing, spread over two levels with three terraces. Better equipped than anything we have seen before in airbnb apartments. There is even a printer! Anything you might need in the kitchen -- but why would one cook in a city that offers so many restaurant choices.
The "private wine cellar" which offers a selection of Portugese wines is a very nice idea. Sure, you could go out and buy your own wine but Nuno offers a wide range of choices (and explanation of the varieties and regions they come from).
We stayed at the apartment for 10 days and it really became our home in Porto.
As travellers who spend a lot of time "on the road" we can wholeheartedly recommend this airbnb!
