my family of 3 had a wonderful stay in berlin, and in part because of staying here at lena's apartment. it is indeed in the perfect location and i think especially so for those visiting berlin for the first time, like ourselves. all sorts of public transportation just within a block or 2, good restaurants aplenty, and a little grocery one the corner. we found much within walking distance for us as well and did much walking being the weather was quite mild for winter.
the key drop off upon our arrival was a tad eventful. the key was not where it was said to be and it turned out it was forgotten about, to be dropped off and all. but lena was easy to get a hold of and worked quickly to get it all sorted out. gela, her housekeeper, arrived with a set and walked me through the first 2 doors and into the courtyard where she then tripped over a poorly placed bike (it was quite dark in the courtyard. hit the button for the light before you go out into it) and fell. she hurt knee bad enough she needed an ambulance. the kind neighbors quickly came to help and after awhile gela, with a smile, handed me the keys to the apartment and told me to go on. lena felt badly about our arrival, and reimbursed us one of our nights stay. i was not expecting such an offer, i found it very thoughtful and considerate. lena took good care of us, as she would you and yours. we'd happily stay here again.
