Oliver's flat is indeed close to a tube station. It is in zone 2, which makes it a little farther/more expensive to travel but it's very convenient to hop on and off at the station just down the block. We never met Oliver during our stay, but were awoken one night with loud conversation in the flat which we assume was him. Checking in was easy with directions/photos sent by Oliver. The flat itself is nice, though it was not very clean when we arrived. The carpet was dirty and seemed like it hadn't been vacuumed for a while, and the bathroom could have used a wipe down on the surfaces/floor. We ran out of toilet paper a couple days into our stay and just bought some ourselves when went to the market; we also ran out of hand soap while there. Having those essentials run out was a little annoying, though Oliver apologized for that. We also couldn't find a garbage can in the apartment so we took our rubbish to throw away at the tube station every morning. This was a good place to stay since we were out and about all day, but would choose different accommodations for next visit. Our host seemed nice, it was a decent place to stay but in a slightly sketchy part of London. I didn't feel comfortable walking around after dark in this area, even with my husband. Nice flat though.
