I stayed for two months at Louisas house and it was wonderful. Her cats are the cutest and I enjoyed using the small garden behind the property for some yoga sessions.
Louisa always tried to make me feel welcome and whenever I had questions she always made sure to sort things out.
The next tube station: Kensal Green is only 10 min by walking which is very convenient. as it only takes about 15 min to get into the city centre. There is also a bus station that runs 24hr.
I would definitely recommend staying here with Louisa and her family.
