Myself and my mum had a great time staying at Petra's place. The room, though small, is very comfortable, with excellent mattresses and pillows and warm bedding. Petra's house is lovely, and she was a very welcoming host - we only met her briefly, but all the info we needed for the house was left for us, including a recommendation for a breakfast cafe, which was excellent. We appreciated the complimentary tea and coffee. The location is great, a two minute walk from Clapham South tube station. Highly recommended!
