Amazing!! This was my first airbnb and it was such a great experience - Antonio's welcome with food on the table and suggestions for where to go in the time we had (only had 2 days in Porto) was great! His knowledge of the local area as well as maps etc provided were brilliant.
The flat itself is in a great location - it was a tiny bit noisy one evening from the outside (but we did stay on a friday night so as to be expected) but is located so centrally that this really didn't bother us! The flat itself is perfect - plenty of room for 2 people and all the facilities were clean and modern. Also Antonio providing a couple of extras such as sun cream, beach towels, orange juice etc were perfect and really made it feel homely and like we were getting a better experience than just staying in a hotel.
Antonio replied really quickly and clearly in advance of our arrival. We were able to check-in early and he provided us perfect directions from the airport (explaining how to buy tickets for example) that made life a lot easier for us.
Overall it was a great trip and Antonio completely exceeded my expectations as a host! I would recommend staying here to anyone based on the great price, location, facilities and extremely warm welcome!
