Nice accomodation in a calm but animated area (Alt-Treptow) in the vicinity of night-life hot-spots in Neukölln and Friedrichshain, but also close to Treptower Park and the Spree.
Good appartment with all amenities for two, and a sleeping sofa for two more. Kitchen and bathroom have all the equipment needed.
Before you book, make sure the WLAN is in operation. During my 2-weeks stay it was down, and was not fixed by the company when I left.
