For what it offered, it was a really nice hotel. We booked the queen room for two people, but really struggled with the space, it was just too small for us. Whoever sleeps on the right side of the bed, needs to disturb the person on the left to use the bathroom which just isn't ideal.
We also found that our bedsheets and pillowcases had red patches on them. I won't say the word in-cass this review is suppressed, but it made us very uncomfortable.
This was just our room though. If you're looking for a nice central place in London, this is it. Just be very mindful about the amount of space you actually have in the room when you book a queen, or consider booking something larger.
