Our time in lima, where we flew from Iquitos, was short and uneventful.
We stayed in the surprizingly grand and beautiful hostal España ($10 Matrimonial room, no bathroom) that looked more like a museum, which it probably was at one point, than a place for backpackers to rest their feet.
We spent most of our time looking for a way to get to Cuzco, and ended up booking a bus, which took us 20 hours, the next day.
