Babel Guest House, Siem Reap
This laid-back GH is on the outskirts of the city and is run by two very engaged Dutch girls. They have a bike rental service “The white bicycles”, which allocates the money to development projects in Cambodia. For $ 1 or $ 2 you can go by tuktuk to the center, the market area and restaurants. They have wifi and restaurant service. There is a boy working there who is learning Spanish and defends himself quite well.
