cozy room/1 room apartment not less than 2 months from May

I am looking for clean, bright and cozy room/1 room apartment from May 1 (+/- several days) for anything not less than 2 months and ideally longer. I am staying in Berlin for at least 2 more years, being full-time employed in an American-German organization. I deal with civil society development and democracy promotion in my work but my profile also includes project management, election observation, grassroot activism and some other things :)

I am 29, non-smoker and a vegetarian (you can have it otherwise, of course). I like people in general and enjoy to have long talks and warm quality-time-spending rather than hard parties. I am easy going girl who have traveled to many different countries - I can never stop enjoying getting to know different lifestyles, value systems and people's way of thinking. Travelling also brought experience in flat-sharing and -renting basics.

My home (=room) is my harbor from everyday stress so the atmosphere at home, however small things create it, is very important. If I share an apartment I'd like to have a good balance of spending time together (cooking or having glass of wine from time to time) and being on my own. But I am quite flexible, so it's totally ok if we have completely separate lives.

I am not neurotic about cleaning, but in general I like to keep my environment tidy and organized. Relaxed and inspiring atmosphere at home is what I would like to have in my new home, and if there are any special requests from your side, it would be helpful for me to know it in advance (in terms of cleaning or something else).

In my free time I like to devote some time to non-work stuff (long breakfasts, movies, books, games, travelling, languages, cooking and just being lazy :))

If you think I suit to be your flatmate or if I sound like a person to rent your place to, write me and I would be glad to meet in person so that we can get to know each other better.
