The apartment is ground level and great for the shops and the U-bahn which is five minutes walk. For the S-bahn it's a 10-15 minute walk making it very easy to get around the city.
The apartment was extremely clean and the linen was on and pressed and clean.
It is a small apartment, but made much bigger by the high ceilings. The kitchen was easy to cook in and the utensils were well thought and again, very clean.
The door is locked with an app on your phone, which works very well and is pretty safe from what I can tell.
The highlight was the speed at which Ilona responded to my messages. All questions answered in a few minutes, which was very reassuring.
All in all a fantastic place to explore Berlin!
