Coming from the North (airport TFS for eg) you will take the highway TF1, direction Adeje/Las Cristianos, take exit 79B LOS OLIVOS. On the big roundabout across the highway go down and follow 'Royal River' or 'Costa Adeje Golf'
GPS coordinates: Calle Alcojora 10 Adeje, but it's 6-9, the house just next to it. Number 9 gives you a wrong location.
Google Maps: We are situated in front of the exit (not the entry) of the Royal River Luxury Hotel https://goo.gl/maps/6o7yEgQHecXwtxYc6
Use your personal code you have got from Hans via WhatsApp. The house is keyless. Go up the stairs, open the main door, and find your room.
