Besides some troubles after the checkin (there are 3 key holes, but only the upper 2 should be used ;-) and the (at least for my taste) loud inner courtyard, it was a nice stay.
The flat is in the courtyard, which itself is located to a house very central in the high life prenzlauer berg area.
If you are hungry or thirsty in the morning, midday afternoon or night, you will find something everytime in the neighborhood.
If you need to do some homeoffice, that's also find. 2 small desks and a good connection make this easy possible.
But, if you dont like steps you maybe would reconsider: it is located in the 5. floor of an old town building (lots of steps :-)
