This is a wonderfully located space. Right near the subway, museums and relatively close to the airport (TXL). I’ve stayed in a number of places in this neighborhood. Ruth’s place has nice style, it’s super clean, easy and it feels local: in the style of older Berlin apartments, not the newer places devoid of German flair. The only issue i would have/advise for travelers is the the internet is quite poor. It wasn’t a problem for me as I have family nearby, but you can’t stream anything or FaceTime, etc. Otherwise, this a great spot. Every time I come back to this neighborhood, there are more amenities (groceries, cafes, food, galleries, etc.).
