This is the best AirBnB that I've stayed at. The location is amazing, close to both the U-bahn and S-bahn which together brought me anywhere I needed to go within 1/2 hour. In addition the location itself is quiet, neighborly, and has ample local resources (cafes, grocery stores, pharmacies, etc). The apartment itself is warm and comfortable. The kitchen is well stocked with all the implements and spices and dry goods you might need (but check with the host first before using).
I am a musician, and this apartment was PERFECT for me. There is an upright piano, accordion, and 2 acoustic guitars which you are welcome to use (very useful if you're like me and spontaneously come up with song ideas that you need to write down right away!). The host also recommended some musical venues and sessions that made my stay better than I could have imagined! I am definitely going to stay here every time I'm in Berlin.
