Great communication with Tom who met us for an 830pm key turnover. He even volunteered to carry my wife's 20kiloish heavy suitcase up several flights of stairs. Place is clean, with strong wifi and completely stocked with basic essentials. There are several restaurants and convenience stores along the 5 min walk to the metro. We felt safe in the neighborhood.
Thank you Tom for answering all my questions and arranging an early morning taxi pick up to Tegel airport on our last day.
