The place was amazing. Both the room and shared area were nicer and cleaner than I expected and good location. The bus from the airport comes almost right outside the house which is great. The host was very nice and responds quickly to the message. She let me in in the morning even the original check in time is at 3. I saw her the next day and she was sweet in person too.
I really recommend this place and I would come back here when I use Heathrow airport again.
