We had a really great stay! We got the keys and the house was literally 3 days for ourselfs. The bed was soft enough and no noises at night, also close to many restaurants and supermarkets. It's about 30 minutes on train to victoria station (central london) and 10 minutes to balham tube. With an oyster card you want pay more then 9.60 pounds a day which you need anyway for the city!
