Stayed there for 5-6 days on our trip to norhern andaman. Got a hut with bathroom, fan and all for 600 rupies. A bit much for us as backpackers but still great value.
The owner Alex is a great guy, had lot's of information and could provide activities around Kalipur. We did Ross and Smith island and could share boat with some others to lower the price. Beautiful trip with nice snorkeling even though the coral is basicly dead. Saw many fishes though.
We also went to Saddle peak with packed lunch from their restaurant. Tough trip! We went without guide. Got picked up in the dark on the way back by alex's staff.
Went to Diglipur with alex in his private car, i did a complete makeover at the local barber, haha!
Alex motto "work hard and be honest" will pay in the end. Great place and very experienced people!
