The apartment could not have more character and the proper old town Porto feel. The view from the river side balcony was the cherry on top. Make sure you bring your camera as I guarantee you will want to take many pictures of the view.
Luis was excellent host, provided all the necessary info (even the weather forecast) and described in great detail how to get to the apartment well in advance and met us at the METRO station.
All in all 5 out 5 stars and would definitely book again
Thank you Luis and thank you Porto.
