We spent about 5 days in Berlin, apartment is well-located if you want to explore the city without losing too much time in transit. It's close to several S-Bahn lines and the U-bahn, and in walking distance of several stores and supermarkets. The place itself is good for 2-3 people! Cozy, easy to find and stocked with the necessities. Alan and Kasia were welcoming, and helpful when we had an issue pretty late in the evening. You could probably walk to the city centre from here, but it would take a while, so be prepared to spend a good amount on public transport!
