We had a super stay in Katie's home. Everything was well organised in advance and Katie was a super host.
The location was excellent and we made most of staying in the area. You are literally a ten minute walk from the wonderful Portobello markets and very close to Notting Hill gate.
It's a great home for families and small groups to spend the weekend. It's very clean and it has a nice communal area too.
There is one room with bunk beds which is on the small side so maybe that's something to keep in mind if your planning on spending a lot of time in the apartment, but it didn't affect us really.
All in all a fab stay and I would recommend it!
