This is the best area in Berlin, near to everything, and yet very quiet because of the other buildings. Sometimes your neighbor plays the piano which you can hear in the background.. The apartment has large rooms which are ideal for couples or a couple with child, not for roommates. The kitchen is brand new, other portions of the apartment are well used, which is to your advantage with regard to the deposit. (if you have a child that makes a mess, this is fine)
A great advantage is the supermarket across the street, Rewe, which has fresh fish and other great items, open until midnight. On the corner is the Neapolitan pizza place, 60 seconds to Napoli. Kastanienallee is great for coffee and restaurants.
