our stay in berlin was lovely. the room is on the bottom floor of yvonne's store and home so it was easy to reach them, if need be. the building is in an incredible location - basically on the border of where the berlin wall used to be (which is now a tourist hotspot) and walking distance to where we thought the coolest area of berlin was.
it's not as "private" as advertised but the curtains help. overall, the value is unbeatable. highly recommendable.
