The keen cyclist found the hoard of around 100 bicycles stacked up on top of each other on a route planning app and added it into her route to Dulwich College.
In the pile there are a variety of different styles of bikes; mountain bikes, utility bikes, children’s bikes and, along with single frames and tyres.
A sign is placed outside the bike enthusiast’s home offering bike fixing services.
The sign also offers the bikes for sale and tells potential buyers they can try them for ten minutes before purchase.
There is just enough space left to get into the front door of the house.
Simona posted a photo of the bike home on Facebook last week, writing: “Someone somewhere in Herne Hill is very busy with fixing bikes.”
The post has received over 250 likes and dozens of comments from social media users.

Speaking today, Simona said: “I saw that some Komoot user added it as a highlight and I found it interesting and added to my cycle plan.
“I was wondering why they are there and will they be piling them up to the top of the house.
“Then when I read the text on a board it made more sense.
“Me and my partner just were staring at it and examining the bikes.
“It’s a very bizarre place.”
