My relatives live there, they have their own house, if you want, you can stay there, there will be no problem, although you will have to live like a family. They have 2 small children, if you want, you can have fun playing with them. If you don't have any problem then tell us we will arrange for your stay.
North Cliff has many budget stays and amazing cafes. You can stay 2 days in Varkala and since you would be going through Trivandrum, you can plan a day for Kovalam backwaters.

Best way to travel is to take train from Bangalore, Kochuveli express stops at Varkala, there are lots of budget hotels in Varkala North Cliff.
Kovalam beach is not very far from Varkala, one more best beach nearby is Kappil beach.
I can suggest to visit Darjeeling Cafe and Caffe Italiano those are my favorites when i visit Varkala beach
