If I could give more stars I would. The place is as pictured and as described. My husband and I stayed at Isabel and Igor's apartment for two nights, and loved everything thing about it. The historic building and the apartment have been completely renovated. Everything about the apartment is beautiful and nicely done. After a day walking around Porto, we were so happy to just relax with a glass of wine in such a beautiful spot. Fresh linens, towels, hotel like toiletries provided, bed is super comfortable. Location cannot be beat, close to everything (one street down from Rua das Flores, close to restaurants, shops, walking distance to the Douro River, etc).
It is a busy, loud street during the day, but with the windows closed you can barely hear anything. There is also road construction going on the corner, but nobody starts working until after 9, and stop around 5 (not a bid deal for us).
