Daniel is a SUPER super-host! Traveling solo - he was very helpful with a map and plenty of suggestions. He also was very helpful and responsive during my stay.
The top floor loft-style studio had ample room as well as amazing views from the small balcony accessible from large french windows. It got a bit cold while I was in Porto but there's two stand-alone heaters that kept the place perfect.
It was a quiet week while I was there, but the apartment is located in a beautiful, historic building so it's not sound-proof, and sometimes there is construction (common in that part of the city as the buildings are all getting nice facelifts.) I'm a light sleeper and it was fine. You can hear a little street noise below, but it's many floors down so not invasive. And when it rained at night, I personally enjoyed hearing the sound on the roof above me as I fell asleep.
The location is perfect! Walking distance to everything great and if needed - quite quick to get an Uber. It's also postcard-worthy. And there's a cute boutique shop on the street level I recommend. I also recommend the coffee shop Fabrica Roasters 2 blocks away!
I will definitely return and stay here again!
