Looking for a place to stay near Norbiton (London)

Dear Internations London comunity,
I will be attending a training at the London School of Coffee and I wonder if one of you can help me.
I’m looking for a place to stay from tomorrow until Thursday in Norbiton area.
A little bit about me, I’m Mexican and I live in Grenoble, France. I’m an Internations consul as I’m in charge of a coffee group in town.
Hopping you will be able to help me.
I wish you a lovely day.
Regards,
Paola
