In October 2010 I spend two nights in the Veggi Guest House. Although stayed 3 months in India this was probably the most friendly and helpful family I met while my trip through India. The Guest House manager speaks perfect english ( not self-evident in India;-))
The houserestaurant with delicious vegetarian food completes the comfortable atmosphere.
They offer rooms in every level of price.
By the way, it is situated only a few minutes walk next to Mehrangarh Fort (place of interest)
So i can recommend the Veggi Guest House!!!
