I stayed at Guido's hotel August 2011. It's on a quiet street in a good location close to River People for great rufting, close to good pizza and other placed to eat and all. I liked security-there is a gate so only guests can enter the hotel and the rooms are away from the street. Bus station is 10 min walk. Many rooms look on a river and you right in front of nature reserve island for a great 1.5 hrs walk to see monkeys. Mejor de todos, the owner is very friendly and no nonsense: he let me use his computer for free, and he is nice to chat with. There is a good views for sunset from the hotel roof and you can also dry your clothes there,too. If it would be me, I would utilize that roof space better and make a place for people to hang out. The door in my room needs to be sealed, but room prices are reasonable.
