Dear Joanna
I have had many conversations with you but you never told me anything,,if you had given me this problem my assistant and I would have indicated to you how to overcome this problem
Thanks for your comment that gives me the opportunity to highlight some aspects of Cusco.

Cusco is 3400 meters above sea level the amount of oxygen in the air is less than the city at sea level and at night the temperature can drop below zero degrees centigrade, so the morning the water must flow in the taps before reaching 50-60 degrees. The hot water in the house is produced by a water heater placed outside of the apartment able to bring the water temperature to 80 degrees.
Cusco has no gas distribution network and all devices are operated with cylinders, when the cylinder ends must be able to change it with the new one
