 We travelled with our 5 year old granddaughter The extra single bed was unfortunately unsleepable The mattress was too thin I tried it resulting in the metal underneath protruding through Very uncomfortable Also considering the 25 degree temperature a room fridge would have been ideal for water etc 
 The wifi was excellent even on the 7th floor as we were probably the best I ve come across in my extensive travels Staff were very good It was soon identified that the extra single bed was overlooked and would be remedied immediately which it was The location was good near to St Pauls Cathedral
