Fulanos it's your best choice to stay in Bogotá for sure. We've been 2 times in bogotá during our stay in Colombia. The first time we stayed in "La Candelaria" but we didn't like it that much, and a colombian friend suggested us to stay in Fulanos (in chapinero) and it was the best choice ever.
Not only it's a really cool hostel, with clean bedrooms and bathrooms, but it also has a great "looby" with a pool table, a great cinema room and a nice bar spot. People working there are really cool and helpfull with instructions and stuff.
FOR SURE STAY IN FULANOS! YOU WON'T REGRET IT!!!!!
