We had one night at Widegate, and the room was lovely. Nice, simple decor. And the location is wonderful.
As some of the other reviews said, the bathroom was a bit weird with water all over after a shower, as there was no curtain or glassdoors. But for one night it is manageable.
I had a small panick on the day off arrival, as there are no street number on the information received and the other reviews said you would get an email on the day of arrival. I didn't get that, neither in my spam folder. When I arrived in London I called the place and I got the street number and was told that there was a reception with a man waiting for me. He was very nice and helpful!
But I would have liked that small part of information beforehand.
