Place is 10mins drive from the main central train station (Berlin Hbf). Apartment is on the top floor (5th floor) which essentially means scaling 10 flights of stairs each time we head out and back. This was quite a challenge with baggage and after a long day out. There's no wifi available in the apartment, TV and radio was not able to catch on a transmission.
The only boon perhaps was a nice cafe located just at the foot of the apartment block where we had breakfast and our daily dose of wifi connectivity.
