The location: roughly 30 minutes from Mitte by train (no need to transfer), but you gotta walk abt 10 mins to nearest banhoff. There's bus but if you come on the weekend it's useless coz they block the road for construction.
The room: spacious and bright. Cozy.
The guest bathroom: was clogged half the time I was there, and it's located on 1st floor while your room is on 2nd floor. Phuong let me used their bathroom which was nice. But it was covered with dirty laundry everywhere....
Overall I had a good stay.
