Susana's place was wonderful. The apartment is just what you need for a short/long stay. Even more I liked the neighbourhood. It's true it is not central located, but this area is plenty of locals (bars & people) which will take your experience in Porto up to the top. You can have lunch for just 7€ (main, dessert & drink) or breakfast for 2,5€ (torrada (portuguese toast you can't miss) + orange juice + coffee)
The house is supercomfy, clean, Wi-Fi works in mint condition and appliances are top quality too. I definitely will come back when visiting Porto.
