Very nice stay in Porto! Comfortable position to quickly reach one of the main metro stations in Porto (Trindade) or the core of the city just by walking. Good supermarkets are located at footstep distance. The flat corresponded in all with the description. Excellent and flexible check-in and -out procedure.
Only one remark: the cars whizzing by on the road below make quite a noise, and they were annoying during night. If you need total silence to fall asleep, bring absolutely some earplugs.
