Diogo's place is amazing, clean, and very spacious. Our favorite part was the balcony. It's centrally located to public transportation, restaurants, shopping, and the port. Sadly, I didn't get to meet Diogo, but our communication via email was great, even after I missed my flight. He was very understanding and accommodating. Keep in mind there's no elevator, so if you have heavy luggage, you'll need to carry it to the 2nd floor. I had no problem. Side note there's a really cute/tasteworthy place around the corner from Diogo's place called Voltaria that you must try! Diogo also has a nice selection of wine that you can purchase, if you're not feeling like going out- very convenient!
I would definitely stay here again! We had a great time in Porto. Thank you for everything, Diogo!
