The apartment is right smack in the middle of Berlin, which was perfect for our needs. We loved seeing the TV tower looming over most of our views and the fact that we were 3 minutes away from the train station was just so incredibly convenient. Plus, the apartment is very large (we were 3 people, but we easily could have fit at least 2 more people comfortably).
The only “con” I would say is that it’s a 3-floor walk-up (6 flights of stairs) with no elevator. Considering we knew this before we booked, I take full responsibility for the difficulties my family experienced in carrying our luggage and groceries up and down the stairs during our week-long stay. Though out of shape, my husband and I were fine doing this walk up the stairs (the huffing and puffing and sweating was good for us). However, my grandmother (75 years old, but very very fit) had a much more difficult time…
So, in all: Great big clean place to stay for healthy younger people. Just don’t stay here if you have mobility issues or are older.
