Nuno is an excellent host! Despite that we arrived very late, he was able to met us personally and very warmly: with port wine and pastéis (thanks for that :) Also he provided good tips about Porto and always was ready to help if we were need something.
The apartment itself – just awesome! Fresh and stylish interior, small and fully equipped kitchen with coffee machine, conditioner, it's very comfortable for 1 or 2 person for short or long term.
Apartment has great location: 5min from metro station, major city sights in walkable distances, also you'll have the best market just 10 minutes away (Bolhão Market). Also Nuno proposed two bikes that you can use absolutely free. Since it located near the lively road – it might be a bit noisy in the early morning (if you like to sleep with opened windows).
In overall: it's very nice apartment with the great service and fair value. It was one of the best staying that I experienced on airbnb! I strongly recommend it!
