I stayed here for one night as I couldn't stay with my friend, so i just wanted somewhere cheap but couldn't stand the thought of being in a hostel for the night. I can't fault the location. It's easy to find and pretty much opposite trafalgar square! So it's well serviced by the tube but being a previous Londoner, I ended up catching the bus everywhere or walking. There's a tesco (supermarket) down the street so if you need a snack etc, it's close by.
The room itself was pretty basic. It's a typical, I guess, uni accommodation. A bed, a desk, a chair and a bathroom. They provided towels, which was a welcome surprise. The bed was a little lumpy. I've slept in worse, but it's not the most comfortable mattress. The bathroom was tiny though. It's literally a wetroom with a toilet and sink. I am quite small but even I had to do a little twisting and turning to avoid standing in a puddle leftover from the shower. Still I think it's not bad. There's no TV or anything, but if you are going to London for a holiday I would think you probably don't need one!
Overall I would stay here again if I couldn't stay at my friend's place.
