I paid about 700rs per night, which is a little more expensive than most other hostels I’ve seen in India. But very reasonable.

They have dorms and private rooms. The dorms have bunk beds with curtains (plus points!), a light, a power outlet, a little shelf, and even a ventilator. Lockers are below the beds. Mind that mattresses in India are generally quite thin and hard.

I found the atmosphere to be mostly calm, with only a couple of people who liked to hang out or go out. There are many remote workers who sit in the common space with their laptops, and there are always people sleeping in the common space as well. The hostel does have a rooftop where you can chill in the evening. 

If the right people are there, they will surely organize a fun activity like a food tour or a night out. I had the luck to join the food tour on my first day and made friends that way. A must!

Moustache Hostel is located in a somewhat gated street in New Friends Colony (Okhla). It feels safe and pretty calm. Nearby you’ll find a market area with some basic shops, good coffee, and ATMs. To get to the Red Fort (central Delhi), you can take a bus, metro, or Uber. They take from 40 mins up to 1 hour. I only went to the center with hostel mates and shared cabs, which made it not too expensive.

They make fresh food every day, so you can easily get up and join in on breakfast (around 150rs). You get unlimited drinking water. The nearby market offers everything you need. Not sure about laundry.

Obviously, Indian bathrooms are a bit of a culture shock. In the hostel, they had Western toilets (with a seat and sometimes even toilet paper) but they were always wet and dirty. The showerd didn’t always have warm water and felt unhygienic.
