This place is beyond beautiful -- Don't think twice, just book it! The views are unlike anything you could imagine, the pictures don't do it justice.
It's also HUGE! Super spacious and very well equipped. The host was incredibly friendly and helpful with local recommendations. It is very well located too, you can walk to any of the main attractions, but the best view is from the Airbnb.
It is a Loft so there isn't a ton of privacy-- you can hear neighbours sometimes and they can hear you, so you have to be respectful. But we had no issues whatsoever, the place was beyond perfect.
11/10 Airbnb! Best views in all of Porto!
