Antonio and GUndega were the best hosts in Porto. Very kind and joyful, they give us very good advices about visiting the city.
Their flat is very lighty, spaceful, calm and functional. THe big balcony is perfect for sun bathing - breakfast - lunch - dinner...
And, last but not least, in 10 minutes walking you are in the historic center of POrto. Add 5 minutes if you want to reach the porto cellars...
As a conclusion, if you have the opportunity to stay there, handle it !!
