We live in the wonderful neighbourhood "Kaskelkiez" on 90m2, ground floor with a terrace and garden. Kaskelkiez has a lovely atmosphere with old buildings and cobble stone streets, it's calm yet lively and family friendly.
We're super close to all the interesting places in Friedrichshain. If you rent a bike you can be anywhere in 5-15min.
Ostkreuz station is a 10min walk away, S-Bahn Rummelsburg 5min and a tram and bus stop 2min.
