I stayed in the apartment along with 3 other friends during the last days of Oktoberfest 2015. The apartment is indeed charming, comfortable and nicely decorated with a fully equipped kitchen (espresso machine a big plus).
Location was fantastic, short underground ride (which is very user friendly) or a 20 or so minute walk either to the city center or to the Oktoberfest ground.
I enjoyed staying in the apartment and would certainly recommend it to others.
