BasKey's place is a good location from with to explore the Atlantic coast of the Basque region. The appartment is as pictured in the photos. As you can see there, the living room has only one sofa where maximum three people can sit, though the appartment accommodates 5 people otherwise very comfortably. It was super clean. Communication was very fast, almost instantenous.
You never meet the people of Baskey though. This is not a problem in that you download a special app beforehand that generates a code and also opens the door directly. However, it also meant that to verify your identity to the local authorities, you have to not only send pictures of your ID, but also take a selfie and send it along to be passed on to the police apparently. That felt strange and we would next time prefer a place were the selfie is obsolete because the landlord verifies that it is you by meeting you and taking a picture of your ID maybe.
