The exceptional house and the amazing host.
There are fews things I like to input from my own 6-days stay experience.
I’d like to say: An Englishlady’s house is her castle：-）
The host: Esabel is kind, knowledgeable and probably could answer all the questions you ask at her.
Being a guest, it is wonderful experience to have a nice cup of British tea /conversation in her house or in the greenery garden or have a leisurely walk in the Battersea park nearby.
There are things you need to be aware:
A smart English cat.
A strong and hot shower in the south-west London.
A pile of tourist guide book might offer valuable information.
A great number of books on the shelf for bookworm who want a quality reading and spirit enrichment:-)
I recommend to stay more than 3 days if you want to explore the city.
