DBL Room, can practice cello in East/Centrl London

I am a Japanese female. I am looking for a double room in East/Central London where music instrument practice is permitted as I play cello in my spare time.

As I ask for such a inexpensive rent, I am happy doing domestic chores.
I'm not good cook like my mum, but I can cook some Japanese food if you request,
If you have any important not-human friend (4 legs, 2 legs, no legs whoever), I am more than happy to look after him/her when you are in/out the flat as I'm not currently working, and staying at home doing my own things a lot

I am quiet and bit shy, but still sociable.
My friends and ex-colleagues say that I'm gentle and soft, likable, comforting, even though I haven't done anything special.

I like going theatre, ballet, opera, (classic) music concert.
I went to more than 20 proms in Summer, from classic music to Sam Smith, and Dr Who!
I also tend to get interest in variety of things. So if you are happy to share your interests, I'm very looking forward for them.

Thank you for your time reading my post
Hope hearing from you soon.
