João was my first private room experience, and I would honestly say it was my best AirBnb experience to date. I stayed with João and his lovely girlfriend Sarah for only 3 days, but I left feeling like we had been friends for years. His home provides all the necessary requirements for your stay, and the room I had was comfortable and spacious. With 4 cats roaming around, you better not be allergic, but as a fan of cats, it was sublime to have them wandering through the halls and sharing a cuddle (if you're worthy). João knows Porto extremely well, and has recommendations on where to go and not to go. I will definitely be back some day to visit again!
