It was my first time with Airbnb and I highly recommend this kind of accommodation. Ian was very kind and helpful with us and he was concerned about our necessities before and during our stay.
The room was lovely, very comfortable and the way we expected.The room and bathroom were really clean and with all the equipment (towels, soap, sheets...). Futhermore, Ian provided us maps and some London information.
The best thing of all is the location. It is worth paying a bit more to be in the heart of London. You won't need to get any public transport, you can almost go anywhere by walking.
I highly recommend this host and accommodation.
