Eva was a perfect host, friendly and welcoming. She helped me to find where I needed to go in Berlin and offered knowledgeable suggestions for exhibitions to visit. The room was better than it looks like in the pictures, with plenty of room for one. Immaculately clean, bed very comfortable and location is quiet.
One should note that the apartment is up four flights of stairs, so you need to be fit enough for that. For a shower you need to crouch down over the bath tub as there is no shower curtain.
I'm sure you will enjoy your stay.
