A Short Note from Mom with more detail. FUN!

"We will actually be working in Callao (it's on the map on the video) which is right by Lima and we'll be staying with Martha where she lives in Mira Flores (means Look at the Flowers!), also right by Lima.  We will see some things in Lima when we are off work - a fabulous water fountain park and probably surfing beaches.  But most of our time will not actually be in Lima - that's just where we fly in and out.  Look at your map & you see Cusco (also sometimes spelled Cuzco in English) - that is where we will fly to go to Machu Picchu - a 1 hour flight over the Andes.  It's just awesome."
