Ann was punctual, the apartment was clean, comfortable and well located by the Hermannstr u bahn in Neukohln. Everything went smoothly. It would good if you spoke a little German as Ann's English isn't that strong. But I'm sure you'll be able to understand each other well enough. Besides she has a book with instructios in English.
Kitchen is well equipped.
If you're into going for a run the templhof airport park right next door is a great place to get some excersize while on vacation.
I would stay at Ann's again.
