Margaret's place is really close to Clapham Junction and getting around is really easy. We went to London, Brighton, Canterbury, and Camden--all easy to get to. The place is nice, the town is really fun and everyone we met was really friendly and helpful. She is fine with putting food in her fridge, cooking in her kitchen, and eating at her kitchen table. Her bathroom is very modern, pretty, and comfortable. Her place is cute, a typical row house. She has a nice little area behind her house that we didn't use, but it's really pretty. She was really good about us coming in late at night, which we appreciated.
About getting there with Maps. Don't use those instructions. From Clapham Junction, go straight down St. John's Hill until you get to Bartholomew Cl. Turn right and go past the garages. You'll find the street her house is on really easily.
Things to be aware of: her stairs are really steep to get to the second floor. She gives you one towel only, and her beds are frankly super uncomfortable. We sent this info to her privately, too.
Fun fact: we saw a fox running down the road late at night. She lives in a town, but you'd be surprised the wildlife around there. Squirrels aplenty. I would stay with her again if she invested in some memory foam toppers. As it is, I took the comforter from the closet and put it on my bed and I was fine. My friend didn't have a comforter and she was really sore most of the trip.
I used to have my own Airbnb and tried really hard to help my guests to feel at home. I don't know if I always succeeded, but feel Margaret did a pretty good job. Except the beds.
