John’s place is a perfect alternative to any hotel room in London. For the same price you’ll get two bedrooms, a lovely lounge and well equipped kitchen, all sparkling clean. The balcony should be great for a drink or light meal in nicer weather and is convenient for smokers (the house itself is completely smoke free).
Kennington tube station is right around the corner, many cafes, restaurants and convenience shops found within short walking distance.
In short - highly recommend!
