Stayed at Dino and Ines' place mid Feb with my Dad for 2 days. The apartment was in a great condtion, stylish and clean. The check in process was easy as Dino was there to meet us. Dino was available on the site and by whatsapp and was happy to provide local info. I believe it was Ines who had also baked a cake too which we enjoyed and that was a nice touch.
Porto is a very nice city and I would definitely recommend this accommodation. Great hosts.
