The apartment is really great and unique! The view from the balcony is gorgeous. The place is tastefully furnished and has everything you may need for a short stay (new washing machine was very useful since it was the middle of our trip). Internet/wifi is very fast (over 100Mbps download/upload). The only two things to keep in mind are the stairs and seagulls. First stairs are the ones leading to the apartment (the hosts helped us with the luggage though!), and then the ones to the loft/bed area which might be a bit awkward to climb. Seagulls can be a bit noisy in the morning, but that might be just everywhere near the river in Porto. Otherwise the apartment is very quiet and we'd still book it again without hesitation!
