We enjoyed our stay at Chirmi Palace a lot, and will definitely recommend it to anyone looking for a quiet yet central place to stay while visiting Jaipur.
The buildings are old, but well maintained and thus only serves to complete the image of a genuine, old-style heritage hotel. The peaceful garden is wonderful to enjoy the hotels well-prepared meals in, and in general ideal for relaxing from a busy day of sightseeing around Jaipur. The staff is friendly and the service good, and the owners personally welcoming us made us feel at ease from the start.
Our room was very spacious, and nicely furnished and decorated in a style that fits the vintage hotel buildings. Two adjustable roof fans and a quiet AC made for perfect temperature. Contrary to what another commenter said, both wardrobe locker and value safe was available in our room, as well as hot water (as with most places in India, you just have to switch on the hot water boiler in the bathroom first!)
