 We rented an apartment across the road from the actual hotel which had all the facilities you would expect but there was no elevator to our top floor apartment 4th floor which was a real pain We had to carry everything that goes along with being out for the day with our 1 and 5 year old up and down the 4 flights of stairs every morning 
 It was almost next door to Earl s Court train station so it was extremely easy to get around to see all the major sites particularly as we were travelling with a pram as well as a 5 year old not too muck walking
