Accommodation / Where to stay
There's plenty of accommodation in Peru and prices vary from really cheap guesthouses to expensive luxury hotels. As normal the cheapest ones are outside centre and don't have warm water or heating. You can survive with them but it might be worth the extra dollars to take a place with warm water and heating as the nights can get pretty cold.
It might be worth booking ahead so you don't need to worry about the accommodation. Atleast book one or two first nights so you get an easy start and can then start to look at other options.
