Had a short two-day stay at Andreas' apartment and was quite pleased with the overall experience, I'd definitely recommend this place to other visitors!
The apartment is located in a back building on the third floor, offering a quiet space away from city bustle. It's extremely clean, tastefully decorated, and had all the basic amenities - large living room and bedroom, we didn't get a chance to use the kitchen but it was fully equipped. The balcony overlooking the courtyard is a lovely addition to the space.
Andreas was quick in responding and was kind enough to accommodate our request for an early check-in. He personally greeted us at the apartment, was friendly and shared some great recommendations.
Location wise, there are plenty of coffee shops, bars and restaurants near by with the U7&8 subway stations just minutes away. Would love to come stay here again for our next visit :)
