Condors are massive birds and no doubt their nests are big enough for a person to sleep in. But if that's a bit precarious for you (Condors are carnivorous, afterall. And big.) there is another option - the Natura Vive Skylodge, Cusco, Peru.
Perched above the Sacred Valley of Cusco, the Skylodge Adventure Suites are suspended 400 metres above the ground against the side of the mountains. Each suite is 7.5 metres by 2.5 metres and offers a 300 degree view of the valley down below. WAY below.
It's not all gourmet banquets and bubbles though (although each suite includes those too) - you've got to get there first. You can walk - or you can take the zipline. Yep, a zipline! So cool! OK, maybe it is all banquets and bubbles.
