Dude, 700 is just not possible. I would still suggest you to take a look at Ginger Rail Yatri Niwas. Agreed it is far and all, but it is well connected due to its location next to a metro station and close to CP. Gurgaon has connectivity issues even otherwise, so if there is a way the training time can be adjusted slightly, your friend can still reach his training on time. Traveling by road is almost ruled out in Gurgaon, rest @chromanic knows better 😀
