Paulo and Sara's place is now in my top 5 best Airbnb experiences I've had. I had been traveling in Europe from the US since September, staying in hostels and by consequence not getting much sleep. So when I decided to visit Porto in December, I decided to treat myself to a whole Airbnb to myself. Paulo and Sara's place was clean, extremely secure, and in the coolest neighborhood in Porto. (Seriously look up Bonfim, it has some of the hippest coffee shops, thrifts stores, bars, restaurants, basically everything you need.) Paulo and Sara always responded immediately to any questions I had and the check-in process was a piece of cake. I would recommend anyone to stay in one of their Airbnb's during their stay in Porto.
