I spent a very pleasant and affordable couple of nights at the Queens Hostel. The entire interior is clean and well-presented, and facilities are meticulously maintained. Guests seem to be screened effectively, so I have no complaints about my roommates.
The hostel is only three or four minutes' walk from the bustling main drag of Shepherd's Bush (so I didn't have to carry any excessive load to and from a weekend of gigs at the Bush Hall), but its location is also very quiet and restful. Nearby we have a number of tube stations for access to various parts of London, plus the main-line station on the (for me) amazingly convenient direct route between Clapham Junction and Milton Keynes. (And across the road from the station we find a Wetherspoons, for emergency procedures before departure!)
The hostel staff were efficient, considerate and attentive, from my making a booking at extremely short notice, to my whisking in and out on a very tight schedule.
On this trip I needed competent facilities in short range and on a demanding budget. The Queens Hostel more than delivered. I will happily come back again if in the area. Recommended.
