The lodge is like a complex of tree houses connected by walkways. Most of the rooms have common walls, but there are a few that are like little bungalows (room nos. 7, 8, and 9). There is no ceiling on the rooms; instead, there is mesh to keep out mosquitoes and to let hot air go up and out. There's a giant thatched roof that covers all the rooms, however, to keep out the rain. You will be able to hear people snoring and talking in other rooms. The mattresses are super-comfortable. The beds are surrounded with gauze-like material to keep the mosquitoes out.
The guides who work at the lodge are great. They all seem to enjoy their jobs and are filled with information. Most of them are pretty good at speaking English. Whenever a guest had an idea for some type of excursion, the answer was always "yes." Even when the guides were pretty sure it was going to rain one night, they still took six people out for a night hike. They came back soaked, of course, but that's life in the rain forest. There are activities all day long. You can do any of them, or none. They have excursions to native markets, animal sightseeing, hikes, etc. On a night hike, we saw giant hairy tarantulas, bugs that light up, and a possum.
Most of the guests at the lodge were very interesting people. There's no TV here, so the guests hang out talking (probably the way many hotels were before the advent of television). You can always just rest in your room if you feel like being alone. The hammock room is great, too.
Breakfast, lunch, and dinner are served every day. I wouldn't call the food "delicious," but it was tasty and healthy. Nothing was fried. You might want to bring some familiar snacks, such as peanuts or graham crackers, etc. There's plenty of purified water to drink.
They have laundry service (done by hand). The clothing is line-dried, so it will take a day or two to be ready.
The thing I missed most while staying at the lodge was hot water. You will have to bathe in cold water, as there are no heaters. I have taken cold showers before in Venezuela and Arizona, but the water here was colder than there. I almost had to force myself to take a bath.
There is no electricity, so oil lanterns are set up at night on the walkways. Bring a small flashlight to use in the bathrooms at night. A flashlight would also come in handy for night hikes (there are much fewer mosquitoes at night, for some reason, than during the day).
Some of these guests were there for 2 weeks. Several were repeat customers. I have not been to the other lodges, but I can't imagine they would be more hospitable than this one. Everyone treated me so nicely while there. Many guests were already talking about when they would return.
