I stayed 3 nights in Astern. I found it to the best 'home' while on my travels. The location is perfect. The room/apartment is simple and stylish and very modern : please keep in mind that the building is built in the mid-19th c.! Marco is extremely helpful and accommodating. He answered all questions and provided recommendations what to do in Porto (in typing left at the bedside!). I would certainly return here again.
