The apartment was outstanding! Big panoramic window, cozy garden, impeccable cleanliness, capsule coffee, comfortable bed, etc... It was definitely the best place to live we have had during our trips.
Also, the big advantage is location in quite peninsula with developed infrastructure like bakery in 1 minute, cafe in 2 minutes, s-bahn in 10 minutes (with fantastic view on lake while walking). My girlfriend and I are crazy because this peninsula has become our favorite place in the city.
So, we will come back to Mandy for sure if we arrive at Berlin again.
