I was traveling alone and needed somewhere to crash near CP in Delhi but as almost everything is expensive in CP, I switched to an area called paharganj, nearby CP only.
The rickshaw wala took 30 bucks.
I booked this hotel online at a deal price of 1200 for a Non AC room.
The hotel is located about 600metres from New Delhi main railway station and around 1 km from New Delhi Metro station, which is very much walkable distance.
There is no restaurant available inside the hotel but if asked, food will be arranged from outside.
The rooms were very nice and tidy . They were large, equipped with Tv. The floor was clean. Bathroom was large and clean as well. There was a large size double bed and a wardrobe present inside the room with a side table. Also, there was one dressing table. Overall the stay was comfortable and if you looking for a cheap and satisfactory option, you should try it once.
And yes Unmarried couples are allowed.:P
