Oliver met up at Victoria station and guided me to the place while giving some tips about transportation and general information about London. This was very much appreciated and made me feel very welcome!
The bed felt fresh and was quite comfortable. The bedroom can also be locked at night if you so desire (maybe also during the day? I didn't think to ask about that).
Before getting to London he also made sure I had the necessary tickets booked for travel from/to the airport, and as other reviewers point out he will help you as much or as little as you want. A pamphlet is provided with information about the stay and things to do/eat.
Having your own bathroom is nice peace of mind. It was clean enough, but could've been a bit better. Personally I had no issue with showering/toothbrushing/toilet. If I was the bath-taking type, I might've desired some more work be done on the tub, but otherwise no real complaints there.
