This apartment was very clean and well maintained. Nicely located close the heart of the city. I can certainly recommend this place.
Since its on ground floor , or slightly below ground floor there is no view. Porto is a lovely city, so you'll be spending most of your time outside anyway.
Important detail that should be known, is that it is an autonomous or keypad based check-in. This gives guest more flexibility and once should ask Luís for the details for the keypad to be sent at 3pm that day. Allowing guests more flexibility as to when they'd like to arrive (something that can be worked out with the host obviously).
