Looking for EN-SUITE double room for kitty & I

Hi all! I'm looking for a place for myself and my kitty Lunna. She's 3 years old and a very funny, but shy cat. She's very quiet and sleeps most of the day.
I’m a 52 year-old Brazilian/Portuguese and have been living in London for almost 15 years now. I work from 9-5, every day in the office (near Borough Station), I'm a Senior Commercial Manager for an events company, so 3/4 times a year I need to go abroad for work.
I don't work weekends, and am a very homey person, so tend be be chilling in my room on Saturdays, and on Sundays I spend the morning and part of the afternoon in church and with friends (out of the house, I don't really invite people to come to mine).
On Friday evenings I volunteer with a homeless project near Charing Cross station, and that's something I care deeply about.
I’m a very tidy person, and I don’t think I could live in a party house, but am happy to share a meal/drink with my flatmate/s every now and then and watch a movie together.
I’d like to have a bathroom for myself, where I could leave kitty's litter box.
I wouldn't want to leave my cat locked in the bedroom when I go to work, so ideally you wouldn't mind Lunna roaming the flat (she is not the type of cat who will destroy everything or sharpen her claws on furniture or jump on tables/counters, so no need to worry. Just as long as she has her bed, she will be walking around a bit and then going back to sleep.
If I sound like someone you’d like to share your flat/house with, drop me a line!
