“A decent option in KB... but only when construction is finished!”
I've stayed at a number of hotels in different parts of Delhi, and Delhi Heights is just all right by Delhi standards in this price range. With the free airport pickup, it's an excellent value and certainly a better option than Paharganj, but the hotel itself is still under construction, and the standards are pretty shoddy. Our bathroom door didn't really open properly, we never really got hot water (as one would expect in this price range), and the hotel restaurant is especially dreary. On the plus side: the room was clean, front desk staff attentive, the location is near the metro, and there was internet available in the lobby. Delhi Heights is a good no-frills option and fine for people passing through Delhi and in need of a clean place to stay, but don't expect anything special. If you think you'll want to spend a lot of time in the hotel, I would look for another place to stay.
