This is a lovely peaceful spot - very comfortable, warm and so quiet (no traffic noise and room just looks out on the garden). Spotlessly clean and check in etc all well organised. We didn’t meet our hosts but they were easy to contact and made sure everything was in order for us.
It’s about 15/20 minutes walk to Clapham Junction, shops and restaurant (or there’s a bus at the end of the road) but if you don’t mind that, this is a great place to stay. The only other thing to be aware of is that it has unshuttered skylights so would be very light in summer - not a problem in December when we stayed tho.
