Liang's place is located 8 stations away from JR shinagawa station (main hub and shinkansen station) and located only 15 minutes away from haneda airport on the keikyu line. The instructions for check in and how to get to the home were clear. Liang's home itself is amazing - three bedrooms, huge washroom, washing machine and air conditioners in each room. Be advised there is a narrow staircase to get to the main floor of the house (difficult for those who have a hard time carrying luggage.) There were a few issues with the connectivity of the Pocket wifi, but overall does not take away from liang's amazing home. It's a very good place to stay during your last few days in Tokyo.
