I stayed here for 5 nights whilst attending a conference. My Deluxe room was a good size, was well appointed and pleasantly furnished. Lots of complimentary bottled water was provided which was much appreciated. The bulk of staff speak some English but not all which was a bit of a challenge at times (my Mandarin needs work...) Some visitors may find breakfast a challenge, I found it best to stick to the Chinese breakfast - unsurprisingly this was better than the Western offer but may not suit all palates.
Yina on the Concierge desk was an absolute stand out. She really took the time to understand my needs and I had an exceptional day exploring Beijing as a result (armed with her hand drawn maps which were surprisingly accurate). She was a delight to deal with.
I'd absolutely stay here again and would recommend it to business and leisure travellers alike.
