Yeah, either stay at the cardboard box or chameleon. Both good. Chameleon is probably better.
I spent a lot of my time in the dorm rooms. Never had any issues with my stuff. People are usually pretty good there. Drops the price a lot too.
I walked to Eros from Cardboard box. Takes about an hour and a half. Not a bad walk, pretty flat. Was just a little hot though!
Or it was 15 namibian to get a taxi I think. prices may have changed a little now though.
