Had a great 2 night stay in the apartment and would highly recommend. Communication with Jonathan was excellent from point of booking. The only slight negative was receiving a phone call from airbnb 2 days before the trip, saying that there might be a chance the booking would be cancelled. I think basically Jonathan wanted to get some reassurance we were genuine people who weren't going to cause problems. Thats fair enough, but even someone with negative intentions would not divulge that in a phone call from airbnb! Seemed a bit of a pointless and stress inducing thing just 2 days ahead of our trip.
As for the apartment, its a really lovely place and all our needs were taken care of, from milk in the fridge to a welcome pack detailing all we would need to know for our stay. The location was perfect for us, a ten minute walk from Paddington station and just round the corner from Queensway with its hussle and bussle and 2 tube stations. We were able to walk to Hyde Park, roughly 20 minutes or so, and on to Oxford Street.
All in all a very enjoyable weekend which has left me wanting to stay at the apartment again.
