Junhee was the best host! all the comunication with him prior the reservation and while you stayed at he's place was amazing. Junhee very responsive and helpful. we asked him to leave our luggage at the last day after checkout, he accepted with no problem, it wasnt obvious.
the apt. was great! just as we excpected it to be. very cosy, fine decorated, had all the things that you need like: city guides, coffee machine, all kinds of tea, towels and everything you need from a place you'll stay for few wonderful days.
It situated in the heart of penzlauerberg few minutes from the M4 that arrives to alexanderplatz in 5 minutes. M10 will take you to the east side galerry and kreuzberg, and to mauer park (great flea market on sundays). and near the s-bahn.
I would definetly come back to the apt.
