Just came back from 10 days with my girlfriend and it was amazing.
The private Balcony has a very nice view, awesome for breakfast :).
The apartment was cleaned everyday (and well cleaned, even the dishes was done).
George is very helpfull (info/rent/transfer airport), the kind of guy you like to have as host, a very good person.
As said in many comments, the apartements are isolated from the crowd but close to Fira center (10-15 min depending how fast you walk), a bakery and some food store at 2 min max, as one bus stop (to go to OIA or to Fira center one stop further).
If we ever go again to Santorin, i'm pretty sure that we will stay few days at Rhapsody again.
Thank you George :)
