The trek was a big challenge but worth every painful step for the incredible sights and experiences!.
Very pricey compared to identical treks that can be booked from hostels in Cusco, but if money is no issue then it is a fantastic trip to book. The guides and chefs were lovely and we were very well looked after. Make sure you take some time (3 days at least) to acclimatize in Cusco before departing because otherwise you'll be extremely breathless hiking.
And be prepared for all types of weather and temperature - we froze on our first two nights then overheated on the third!.But overall it was an amazing experience !!.
