We went to Katherina for the authentic house and great view and we got what we expected to get. :)
If you have a car no problems at all. If you don't so you'll have to do some hiking to get on the top where the house is located. It's a 30 minutes lazy walk to Acropolis and a 40 minutes lazy tram ride to the sea. Katherina and her family were very friendly and helpful but we didn't want to bother them much. :)
