We stayed in this flat for 4 days. The flat is really pretty and got everything you need. It’s really central, you walk a few minutes to the next train station and are in the city centre of berlin in a bit.
We had some struggles with the heating. When we arrived it was super cold and over our stay we didn’t really got the flat warm, which made everything a bit uncomfortable. Because of that we would recommend a stay at that flat especially in the warmer months.
