I didn't meet James in person. He constantly messaged me and made sure that I was comfortable. His flatmate was very kind and helped us with a lot of information as it was our first time in London.
Room and toilet were clean and just what we needed. Although the room was cold, the bed was heated. There are a lots of cafe/pubs around. 'Stuzzico' was my favorite. It is just a couple of blocks away.
Location of this flat is unbeatable. It is very close to Paddington station which connects you Heathrow airport (Heathrow Express) directly and also pretty close to other major landmarks.
