Lena's apartment is just lovely, reminded me my own's place - spacious, clear, minimalistic, with an artsy attitude and eclectic twist. Absolutely in love with Lena's taste in interior design and quality furnishings. If you plan to have Kreuzberg-Mitte type of holidays - this apartment is just perfect for logistics.
Talking about advantages Gorlitzer Ubahn is in 5 min. walk, Spati - just on the corner, the best classy coctails bar Schwarze Traube - in 1 min walk, super awesome Markethalle Neun market with thursday's street food festival and sunday's brunch - just there:)
I would totally recommend this apartment, very good value for money.
