 Nothing at all It was a perfect stay 
 Staff are extremely attentive Had a phone call from reception shortly after we arrived in our room to check we were happy with everything and then when we got back to the room on our first night there was a hotel postcard put through the door asking was everything ok Lovely touches The hotel is stunning and we had fab views onto Buckingham Palace Mews It was a great location for getting around everywhere Would definitely recommend this hotel and would stay again tomorrow The Red carnations everywhere were a beautiful touch
