I booked a very last minute trip to the beautiful city Porto and luckily enough this apartment was still available! Ana and João are very friendly people. They told me nice things about the city (where to eat and to go) and I feel really welcome.
The apartment itself has everything what you need and is design-wise very well thought (great job ;).
The location is a little bit outside the touristic center, which for me was perfect (everyday a little walk, so you see a lot from the city). And Porto is not a really big town so you can do everything by foot.
I definitely will come back to Porto once and really recommend this place!
