The apartment is definitely the best: in a very central location, close to major tourism spots, with lots of choice of restaurant and shops nearby. It is very clean, well equipped, spacious for two people, bright with sunshine.
More than that, Andre is the best airbnb host we've met so far. He gave plenty of advice, recommendations on where to go, where to eat and what to do, even before our travel started. Unfortunately we did not meet him in person (by the way, auto check-in is clear and quick), but he was with us almost everyday with new suggestion, care and reminder by message.
Stay in this apartment is part of great memory in Porto. -- It's not just a place to stay, it is about people, even those you never meet.
We highly recommend to anyone travelling to Porto. You'll enjoy it.
