Me and my friend stayed with Rui & Sergei for 5 nights.
The Appartement and the room were exactly as on the photos. We have to thank them for hosting us. Both are nice and welcomed us warmly. Theit house is a little bit far from Porto center. But still easy to find in Villa Nova de Gaia. During our stay there was no trouble and both gave us a sneak peek about the hotspots in Porto, the living environement and Portugals legend of the roast cock of Barcelos. Their 2 cats are adorable!
I would definitely recommend them to other as hosts.
