Argentinean programmer looking for a room

I'm looking for an en suite double room in a friendly home.
I'm an engineer working at a great startup in central, and would love to have a commute no longer than 30 minutes. High internet speed would also be necessary as I work from home once a week.

I'm 26 and I moved to London from Buenos Aires about a month ago. I speak English, Spanish and a little bit of Portuguese. I love reading, watching films and going to the theatre. Also going for walks no matter the hour and going on unplanned trips on weekends :)

I'm also a vegetarian but don't mind what everyone else eats. I usually eat out although I'm trying to cook a bit more.

I'm new in the city and already have family living here, but would love to make new friends! Also, plus points if you have a pet, as I couldn't bring my pets (3 cats and 2 dogs!) with me.

Ideal moving date would be by the end of March but would consider depending on the place.
