Joana is very responsive, she responded very quickly to all my emails and gave me valuable information for my trips (from airport to appartment for exemple)!
Location is excellent, betwenn ribeira and shopping zone, also near night life! The apartment was clean, new and extremly comfortable!
Don't forget to visit the small coffee (bakery) just down the building, the Joana's sister will makes you the best "tourada" (special toast from Porto) with excellent real orange juice!
