If you choose this place you will probably stay in one of the most cozy, exquisite and wonderful places in the city of Porto. And - even better :-) - you will be able to meet Diogo as your great, most knowledgeable, witty, smart and stylish host. Ask him anything about Porto!
I can only confirm what has been written here before: Super place, very close to all the sights in an old building, easily reachable on foot and very quiet at night. You'll have all of Porto right on your doorstep. Apartment is furnished in a very authentic and elegant manner and you will find anything you need - really a great place you will want to come back to soon (like me!).
