I've spend a lovely day exploring all the nooks and crannies of the blue city together with mister Singh. He's been an outstanding guide, quick to respond, and a good source of knowledge of the sites we visited together. The only comment I have is that sometimes he goes a bit too quick, if he believes you're probably not interested in something. Just ask and he'll slow down and show his knowledge about these topics too. Wholeheartedly recommended. He'll help you any way he can, above and beyond just being a guide. More akin to being a friend!
