This is a different experience.
The Pro's - excellent location especially at the price. Room is nicely fitted out, and bed is comfortable. Queries are handled over WhatsApp as you have no phone in room, but not by someone in the property (possibly even AI) but prompt and helpful. Corridors on the accommodation floors are accessed by key card and you can only access those in which your room is located, which improves security.
The Con's - it is extremely compact. It is pitch black, but you can leave a frame of light on a dimmer to see by. You have less about 1.5m2 of standing space, there are 2 hooks for clothes hanging, and the sink is so small it was hard to get my head over it enough to clean my teeth. In addition, my room didn't have any toilet roll - I had to request this from reception, but it took 3 attempts before I found someone there. I also had to request a hairdryer, which is complimentary (Knightsbridge location, others have a beauty room you can access) but not in the room by default and has to be picked up from reception. When there, the reception staff were helpful and friendly.
A second stay would be easier as I would know more what to expect, but this isn't somewhere to stay long, and you can't really work in your room (except lying in bed). As a place to sleep with reasonable security it was fine and the price for the location really is excellent.
