We booked this stay for our son's 4th birthday as we were visiting the Natural History and Science Museum. The staff at the front desk were very welcoming and friendly, and the location for both museums is great.
However, the family room that we had booked was tiny and there was no space for the travel cot that we had requested (of which there was no sign of in the room anyway). We asked to be moved to another family room; the room we were given was no bigger but when we moved a small table and chairs we were able to create enough room for a travel cot, which still hadn't arrived - eventually arriving after we had made two phone calls to the front desk, followed by two further calls to request bedding for this (my daughter ended up using a sheet and a towel as a duvet as we were given a thick king size wool blanket when we asked for a quilt for the cot).
The room smelt of cooking, the windows did not open and the air con didn't work. So it was hot, smelly and stuffy! Add to that it was noisy as the air con generator was directly outside of our room. All made worse by the fact that there was no hot water at all in the room, and we had to use the shower in another room in the morning, which was at the opposite end of the corridor (so that's the 3rd room now, for an overnight stay)
A terrible experience in a hotel that is not at all suited for families.
