I experienced a warm welcome from the beggining. Jon is a perfect host with great hospitality.
In the flat, it was totally artistic with essence of Denmark, you might find stuffs with borders in red and white. I found everything in the flat very comfy. Although the flat was located on top floor without lift, I didn't have much trouble. On the day of arrival, Jon even helped me with laggage when we are going up to the flat. Cooking utensils are fully equiped so that you can cook yourselves almost everything ( of course surround area offers variety of eat-in and take-away ).
I highly recommend for your Berlin stays.
