Luis was great. Super nice, timely, and very helpful.
The apartment is big, the patio is exactly as in the pictures and maybe even better.
It's a nice 10-15 min walk to the center and most local restaurants.
There is a parking garage underneath the building which Luis was kind enough to take us to. It's 12-14 Eur, which isn't bad.
The gulls are there in Porto so you may have to close the windows but I doubt Luis could have done anything about it :)
