Ben's place is immaculately clean and has a great, fully stocked kitchen (fridge, microwave, plates, glasses, washing machine, etc.). There are 2 toilets and 2 showers for 5 rooms which was more than sufficient. My room was a single- a bit on the small side but absolutely sufficient for my needs. It was also extremely quiet. Ben's communications were personable and friendly.
The location was outstanding. Battersea park is an amazing location and I found myself an easy walk from many locations.
I HIGHLY recommend staying there if you find yourself in London.
