We stayed at this hotel a few times. The rooms are OK. The linens are not spotless, definitely had not been changed but this is normal for Indian hotels/hostals (unless you go to upscale places), so bring your own if you wish. Also if you use the AC, there is no blanket and it gets pretty cold. I had my sleeping bad.
The first time we stayed the AC worked the whole time and the room was freezing. The next time, the AC was turned off through the main switch downstairs so it got stuffy and hot. Complain and ask for a discount if this happens. Everything is negotiable in India!
Rickshaws and taxis are easily accessible, the staff will even fetch you one if needed. Friendly, safe, hot water, good price.
Located in Paharganj, metro station (Rama Krishna) is 2min walk, plenty of dirt and beggars, so if your first time and day in India, be prepared to be shocked.
New Delhi railway station is super close and a ride with a rickshaw should be no more than 40-50 rupees. Nizamuddin is farther away.
