Imme was very approachable and her flat was really clean and nice, just like the pictures! When I arrived it was bit warm in Berlin so slept with the window open but woke up multiple times in the morning as the main street was quite noisy but besides that, it was a wonderful stay. One thing to add is that the wifi signal wasn't so strong so had to use the roaming instead. I spent most time outside so didn't bother me much but should be aware if you are looking to bring laptop, etc.
