YHA London St Pancras' location is great, just a few blocks from the underground on a busy avenue. It is pretty safe -- there's a surveillance system and a quite new elevator. Rooms are pretty quiet, there are individual lockers inside the rooms and some more in the basement in case you need to check out and leave your bag there.
Breakfast is great. There's a laundry, kitchen, and TV room. The hostel also has internet access although it's cheaper at McDonald's. The hostel also has an exchange but there's a fee for that, so if you have the chance, exchange your money at Heathrow Airport. The staff is helpful and you can get some assistance there including tour bookings, calling cards, and underground and attraction tickets.
Now the downside -- the bathroom. It was clean although there was no sign of cleaners during our three-day stay). The shower space is really tiny -- you can't get inside and wash your hair properly, because the water flows against the wall. But it's worth it, we would definitely stay again.
