Had an enjoyable five night stay in June with a friend in one of the two twin bed rooms, facing the interior of the building, so very quiet, albeit a small space. Our room was ready for us when we arrived early, which was a huge bonus and very appreciated. We were here during a heatwave, so the air conditioning in the room was a true lifesaver. The "closet" was a wooden bar with four clothes hangers sticking straight out from the wall as you walk in the door.
A note about our bathroom was that it was not well proportioned. The giant shower took of two thirds of the space and had no storage of any kind inside of it (it did have great water pressure though). The sink was a foot across at absolute most, with very little counter space to hold anything. The sliding door/wall was lightly frosted glass, but not all the way to the floor which was a little odd, so don't expect total privacy in there.
Lastly, the electronics in our room weren't operating properly. One of the lamps by the bed had burnt out and the "suitepad" that controlled the TV never worked. We were able to plug an HDMI cable into it and watch our own shows though.
For most of the requests we did make, the staff were very accommodating and attentive.
The hotel is in a fantastic location for travel around London since it's so near to the Euston Square and Warren Street underground stations and many buy stops. Lots of food options and grocery stores within walking distance as well.
