This was our very first experience with AirBnB and it was everything we thought it could be. We spent two days at Karen's home, using it as our base to be typical London tourists. Karen's house is an easy and enjoyable 3-5 minute walk from the Train Station and any map program should take you straight to it. There were a few pubs nearby as well(We ate at the Sun one night and it was great!)
Our flight arrived from the U.S. In the morning and Karen was very accommodating to let us come by and drop off our packs before heading into the tourist zone. She gave great advice on travel, sites, and food. We had a few lovely chats, but largely we were in the city "touristing" most of the trip, just coming back to sleep and shower. We communicated with Karen mostly via the messenger in the AirBnB app, as our mobile phones are U.S. based. Karen replied near instantly every time.
Karen's house is very nice, clean, and well kept. Having the ensuite bathroom was great; we felt like we had our own little apartment! Karen also showed us around and gave us access to the rest of the house and the garden if needed.
We would be honored to stay with Karen again when we come back!
