My wife and I stayed at Sabine's apartment and we would definitely stay here again :) The apartment was clean and warm when we arrived and was very welcoming. The bed was super comfy, and the blankets nice and warm.
Sabine's apartment is located in a great area. We made use of all the amenities (washer, dryer, coffee machine) which were very convenient. Very close to transit stations and markets, plenty of stuff to do.
We found it close enough to most of the major attractions to walk everywhere. Sabine has excellent communication and responded quickly to all our questions.
Highly recommended.
