I think you will find Jan is right Kev. On the many times we have travelled up to Ipsos from Kontokali on the No7 (the only blue bus on that route) we have had to terminate the journey at Dassia, and then get on a Green Bus. Alternatively we have taken the Green bus from Kontokali opposite the supermarket to Ipsos.
I dont know if this is a new thing, but this was happening in 2002, 03, 04.
Incidently, a quote from a Greek tourist site states the following:
Over the past years, the village of Dassia has become a highly cosmopolitan resort which offers a wooded bay and a beach of pebble and sand. Accommodation, restaurants, cafes, bars and night clubs can easily be found in Dassia.
This I think is the EDAM CLUB, DASSIA.
