The staff were very helpful. I was particularly impressed at how quickly they got an iron and ironing board to me when asked.
I would have liked to have a fresh towel, and to have the room made up between my first and second nights, but apparently that needs to be requested more than a day before, which is less than ideal on a short visit. I'm sure if I'd asked, they would have done it, though.
Generally, I was impressed and happy. Apart from the very, very bright green emergency exit light which could not be turned off. I think it's a legal requirement to have one, but surely they could get a dimmer option.
Other than that, though, great little place, excellent location, good value for central London.
