Nice house- it's old but homey and confortable for our stay, with lovely furniture.
We went with a 1 year old baby and it was perfect! his own little bed, a baby chair and lot of toys which helped make us feel like at home.
Only thing to be improved is the matress... a bit smaller of the bed structure so sometimes was a bit unconfortable.
Lovely neighbourhood, very good situated, both going by a walk to Alexanderplatz and going for a quiet walk to discover Prenzlauerbeg parks, restaurants, bars...
