Olivia's place is quite well located from the public transport and is in a walkable distance from two tube stations, which is advantageous for those keen to explore SW part of London. I stayed in Olivia's En-suite Room which was well furnished and facing her back garden from where you can hear birds singing when you wake up in the morning.
I found lack of door between the bedroom and the bathroom quite not my style and also I had issues with the running hot water from the shower which caused some serious frustration during my stay.
For first comers to London/ area she prepared detailed notes to help them getting around, which I found quite useful.
