Loved Tim’s little space! It’s very cosy (as long as you don’t want lots of space, it fit 2 adults +suitcases). Tim went out of his way to let us in to the apartment when there had been a mixup re: check in time (very appreciated!) and Marble Arch made for a relatively central visiting point (walked through Hyde park, <10min walk to 2 tube stations on different lines, and ~20 min walk to Paddington st - where the Heathrow express finished!). Thanks Tim!
