The appartment is not even 5 min away from the public transportation (I recommend to use the U, it takes you 30 min to get to the Branderburg Gate). If you're going to see the city, the daily pass works great; you buy it and you can use it as many times as you want if you are going to see the city. The place is clean. The room is big enough for 2 people (may be more). Elnaz's mom is a sweet woman. She is always willing to help you). We had a great time at her place.
