Kostas was a fantastic host - and gave excellent advice on where to eat / what beaches to go to. He also had some good ideas for where to take our two children. Honest about things to watch out for (traffic and parking in the north of the island) which we really appreciated. He arranged transfer from the airport / to the port, as well as car hire when we were there. Would highly recommend Blue Dreams for people who want to stay in the quieter (better in our opinion) part of Santorini while still able to get to the more touristy part.
