My girlfriend (Kat) and I (Josh) are two lawyers from Brisbane, Qld, Australia and we have moved over to London to work/holiday. We love travelling and travelled three months around Europe pretty much exclusively with Air BNB.
We are both lawyers and so aren't at home that much on the weekdays/weeknights and only home marginally more on the weekends. We can show you as much or as little of the area and London itself as you require.
We are both quite laid back and really just want to ensure that your stay in London (and our place) are as enjoyable as they can possibly be. We will always try and do our best to provide whatever you need, all you need to do is ask :)
