I used TOUR IN PERU 2 years ago. They are a husband and wife agency that really takes care of you. If you are missing some details I would just Skype, email, or Facebook message them. My experience with them was grand, safe and they picked us up from the airport, were our tour guides in Cusco until we left for Inca Trail and took care of all accomodations. My actual tour was perfect and the guide was really great. I travelled with my sister and we ended being in a groups of 9 or 10.
If you go with them you will be happy 🙂
Enjoy the trip!
