It was a beautiful stay in Porto!
It's a great city and i recommend everyone to go there. The appartment was very cozy and nice, absolute top quality.
One thing though was that there were no real shades to cover the windows at night, and because there is no door for the bedroom, the sunlight (or the streetlight at night) did shine through. I personally had no big problem with that, but there are people who like their bedroom dark.
All in all a great host and a beautiful city. Definitely recommend it!
