Ersi villas is a superb place. The rooms are great with everything that u need. Elias is fantastic. He transferred us to/from the main bus terminal and the airport. He explained and gave us advice on everything that we needed and gave us maps. The location is excellent - in firostefani which is better than most other places. You can hire quad bikes from the villas for €23 per day. U can see the whole island this way. If you miss your pet, Magas, the friendly family dog roams around. We highly recommend Ersi villas to anyone who visits Santorini.
