I had a lovely time staying with Anna and the family. they arranged a free transfer from the airport which was great and even helped me book a tour and then drop me to town.
karterados is about 30 min walk to Fira but it's a stroll I enjoyed doing as it meant I was sure to have my exercise.
the pool is absolutely lovely too and I had no problems with showers back in my room too.
I'd recommend this place if you want to be close enough to the action as there are cafes and restaurants in karterados, but not slap bang in the buzz of Fira :)
