Ya has been my guide and companion for the last 4 days and I could not be more happy with his services. He is a very knowledgeable person both in history and in showing the right spots according to my wishes. He has also included me in several outings to dinners, bars and clubbing, all feeling very close to hanging out with a mate. And finally, he has always been available with quick replies whenever I have been in need of some advice. I wholeheartedly recommend Ya as a companion/guide.
