Rob is a fantastic host and this apartment is great. I stayed here for a week in March and by the time I left I felt like we were old friends. I'd been to London before, but Rob was great with explaining the basics about the neighborhood and closest buses, tube, etc. The apartment was really clean, in fact the housekeeper came twice while I was there. Great views from both the front room and the bedroom. While I did have my own bathroom, Rob's shower was not working while I was there so he used mine, but I believe this was a temporary situation. If this matters to you, I would just ask about it. I ended up having a friend stay with me 2 of the nights and Rob was very flexible about it, which I appreciated.
As a woman I liked that this was in a doorman building with 24 hour security - definitely felt safe. Location-wise, the building is on the edge of Notting Hill and Ladbroke Grove is the closest main street. Great access to buses (which are super efficient and easy to navigate compared to NY!). The closest tube station is Ladbroke Grove, about a 10-15 minute walk from the apartment (but you can take a bus to the station and then it's even quicker).
All in all, it was a great stay for me and I would certainly consider staying there again for a future visit. Thanks Robert!
