Darren's spot offers great value and a very convenient location. It is only a couple minutes to the nearest Tube station (Nine Elms) and in a very quiet neighborhood. We were never disturbed by any nighttime noises. The kitchen is very functional and, combined with the Sainsbury's supermarket at Nine Elms station, made it easy to cook a lot of meals there.
The unexpected bonus for us was Battersea Park. It is a beautiful, verdant oasis and only about a 20 minute walk from the apartment. We took advantage of it repeatedly when we needed a break from the chaos of London's shopping and entertainment areas.
Darren communicated quickly whenever we had a question. I'd rate him as a very capable and friendly host. The only item that was lacking was replacement light bulbs for the bathroom. Several were burned out when we arrived and we replaced what we could from stock on hand. We were visiting during Christmas and he might have had family obligations.
