I have been to Tirupati Balaji recently, where in we needed a hotel for night stay, so that we could proceed for darshan in early morning. We chose ASR guest house for the same. The hotel when we reached there was above our expectation since the price were too low. The receptionist & other staff was very cooperative. The room was also very spacious & clean. Furniture provided in the room was also up to the mark. Also we got an added advantage of the location, as all good restaurants were at a walkable distance from the hotel.
Overall, it was a good deal.
