Fantastic location, ultra central. Rest is just fine. Their ball room area is super nice for business meetings, private events. Clean, with descent size rooms.
The playroom is very sparsely furnished. What you see in the picture is basically everything. I was told that it was only available during breakfast but was allowed access if a parent is present.
Don't expect to get any calls answered if you use the phone in your room. Tried to email to book an airport collection before I left London - no reply! Arrive at 17:45 to check in ... Room not ready!
