I stayed for four nights around my trip to the Inca Trail/Machu Picchu, and would definitely rebook if I am back in Cusco. The staff were so lovely and ready to answer any questions I had. The beds were warm and comfy, even though nights in Cusco are freezing, and I slept really well. The showers were also always hot. Breakfast was something different each day (eg. omelette, pancakes), plus bread, jam, tea and coffee. The only downside is it is further away from the centre than other hostels, but the walk is easy and tour companies will still pick you up directly from this hostel for trips to Rainbow Mountain/Sacred Valley etc.
