The best features of the dozen comfortable rooms here, in three modern buildings built of glass, steel, and wood, are the private balconies cantilevered over a forested ravine, perfect for bird-watching. Each room is named after the exotic plant growing at the doorway. The smaller rooms have two single beds, and larger ones have three singles. Bamboo furniture and botanical prints keep the rooms light and fresh. Ask for one of the recently renovated rooms with refinished wood floors, new crafted-wood furniture and freshened bathrooms. Rates include three hearty, home-style meals, a guided tour of the grounds, and 24-hour access to the garden. Staying overnight is the only way to see the garden at dusk and dawn, and you can walk the Sendero Río Java, a trail that follows a stream through a forest with birds and monkeys. The staff here is cheerful and professional, and the youthful enthusiasm of visiting research students is contagious.
