One of the best stays I've had! Celestin is the perfect host!! He makes himself available to answer even the smallest of questions and will go out of his way to make your stay more enjoyable. For example, I tend to be very sensitive to mosquitos, and he installed a whole new mosquito net in the room I was staying in! He was also patient with me when I had to change my schedule a couple times and was supportive throughout the process of booking and rebooking.
Celestin's place is perfectly located--all the major sights to see are within walking distance or a short uber from his place. If you're a light sleeper, make sure you bring earplugs for city noise. Great value spot!
