We had a fantastic week at Renato's! Such a perfect location for exploring Porto. You're just near the end of a major pedestrian-only street, with tons of shops and restaurants at your feet, but absolutely quiet for sleeping. We thoroughly enjoyed our stay in Renato's spacious apartment. He is an attentive, thoughtful and knowledgeable host, who goes out of his way to ensure you have a great experience in Porto.
P.S. We didn't need a car for Porto, but when we decided to take a day trip up the Douro Valley, there was a Hertz a block away. Cheers!
