Prime location, comfortable bed and pillows, great water pressure. In terms of the flat, I really couldn't ask for more. Mario was such a gracious host. He was very communicative prior to my arrival, and provided clear instructions for check in. When I got into the flat, I saw an absolutely adorable map that Mario prepared for his guests, which outlined his recommendations for visiting Porto. We spoke over the phone so he could welcome me on my first day. He has the sweetest cleaning lady, and a lovely wife! I'm mildly disappointed that I didn't meet him personally, but that's only because I would have loved to thank him in person. If you are visiting Porto, please stay at Mario's flat for a great experience!
