The view!!!
This apartment's biggest selling point is the view and the location. It's easy to get everywhere and it was a quiet and restful place to stay. Jan was helpful, kind, and communicative and the newly updated Berlin guidebooks that he left are a really nice touch for visitors. I could tell that Jan wanted his guests to be happy.
However, if you are sensitive to dust, be aware that unlike the photos, the apartment doesn't have hardwood floors... there is a brown low pile carpet that has been cut and placed all over the wood floor. The couch has also been covered with a rather unattractive brown cover. Finally, the mattress could stand to be replaced.
These details did not detract much from my enjoyment of the space, but it doesn't look exactly like the photos in the listing.
Overall, I would still recommend this place for a nice stay in Berlin. I'll always remember that view!
