We stayed at Jennys place for a week- absolutely wonderful experience!
The apartment is cozy and welcoming, location is convenient . Pubic transportation is right outside, a short tram ride will take wherever you need to go.
Also a huge supermarket across the street as well as a 24hrs kiosk.
Jenny was super friendly and communicative.
Perfect place for a convenient, homey and budget stay in Berlin, would definitely come back!
