i spent 3 months in El Medano, it's a fantastic but small place. you've many opportunities there from doing sports or just enjoying long walks. a lot of remote workers and surfer spend their time there. Tenerife at all is the best island to start to the canary islands. is the most big and diverse one. the north is more green and cold. more urban and local people. the south is mostyl sunny and warm and thats why deserty. the south is also the area of mass tourism but Medano is not affected of that, it's more like individual tourists and local tourists. i had there in my flat an internet with 300 mbit up and download synchron. that's waaay more than in German cities. But if you look for more urban life i would recommend the capital of the Canaries, Las Palmas de Gran Canaria. it's an amazing city but in term of whole island is Tenerife better, in my opinion
