Gili's apartment is exactly as described: comfortable, clean, pleasant. The neighborhood is full of life (cafe's, restaurants, bars & clubs), but the apartment is in a quiet street, that allows late morning's sleep...
The U-ban station is a block away, & also several bike rental places, which allows great site seeing of the city.
Gili was available, nice, and helpful (though no help was needed cause everything was tip-top).
We strongly recommend the stylish X-berg for any couple traveling to Berlin!
