The location was unbeatable, and I would definitely stay here again! Marco was very responsive leading up to my arrival, and we were greeted promptly when we arrived to check in. Room was just how the pictures portrayed it. Great view across the river.
Some reviews talked about the noise, and I agree. Windows opened or closed at night, there was still quite a bit of noise. Loud in the morning too, because tour buses pick up right outside. It wouldn't deter me from staying here again, but it can be very noisy outside, if you're a light sleeper. This is a slightly picky comment, but the bathroom has an odd set up. The doors have normal glass, no curtains or blinds. Kind of awkward if staying there with a friend. I stayed here with one friend, and I think two adults is more realistic, instead of four as advertised. There is a big bed in one room, and a pullout couch in another area. You could fit four, but two people worked better for us.
Overall, it was a great place to stay at, amazing location, secure accommodations (always felt safe), and good value. Highly recommend you consider this place if visiting Porto!
