The apartment is simply beautiful- walls lines with books, comfy chairs and wonderful views onto the courtyard from our bedroom window. The bedroom was clean, roomy and wonderfully decorated.
The hosts themselves were friendly and accommodating- Irene and Christoff were happy to offer recommendations, extra food and help around the house. Very lovely people to have a chat with in the mornings.
The apartment itself is a little out of the Berlin center, but is easily accessible via public transport, with the train station 5 minutes walk down the road. To get to the center it takes around 20 minutes with a few train transfers, but trains come very often.
The area doesn't have many places to eat out, but it does have plenty of supermarkets, bakeries, fruit shops and banks, so shopping and cooking at home is an option (and encouraged by the hosts).
Overall, a wonderful stay in Berlin; I would recommend Irene and Christoff's apartment to anyone and everyone
