I strongly reccomend this place, Elefteris and his wife are extraordinary host, the place is outstanding, with everything you can need, they clean the apartment everyday and you will have your towels dry and clean everyday too.
The place is very close to the bus stop for going to Thira, to the airport and beaches, if you rent a car, then a parking area is at 20 mts (twenty)
We were 5 and had a great and pleasent time in Santorini.
