Pension Livadros is a small and beauty place in Karterados. Maria and George are very polite and they are ready to help you for whatever you need: for example George went to the airport to take us at 1.00 a.m.!!
My room was small but very organised; the pool is clean and all the pension is beautiful. In Karterados you can rent a car or a scooter to go to see good places all over Santorini.
I strongly suggest to stay in this pension!
