Had a great stay in London at Xiao’s place. It’s right next to the Paddington train station, which is a 15 min ride to/from Heathrow and a tube ride to anywhere else you’d want to go. Plus the neighborhood had lots of nice pubs and restaurants. The place itself is stylish and clean with lots of room. It’s a walk up (which they stated) but it didn’t bother me much. Would definitely recommend!
