conservation scientist looking for a room/studio in Berlin for nov-dec 2015 :D

Hi! It's Gaia here!
I am 31 year old conservation scientist and I will move to Berlin for a couple of months (Nov-Dec) for an internship at Rathgen Laboratory analyzing art pieces.  
The lab is close to Schlosspark, so I am looking for a well-connected furnished single room possibly in Charlottenburg or in a central district. My max budget is about 300-350 all included.

What about me? I am easygoing, sometimes chatty and sometimes quiet, it depends on the day. I love tea and making cookies, I am not vegetarian but I am used to veg meals (my boyfriend is). I will probably work all the day long and get home late tired...I'd love to find a cosy home with nice people to cook and have dinner together and this sort of things :) What else. I don't smoke. Love cats &dogs. I don't understand a thing of german, but I am planning to learn enough to accidentally say " I got that word!! The rest is nonsense, but whatever, I got one!". 
Offers from families are also welcome, in my 20s I had a lot of fun being an aupair in UK ;)

Let me know, tschüss!!
