We have had a great stay in Kirk's house.
The location was very accesible to town like Alexanderplatz where you can find places to shop and eat. Also the subway station was about 5min walk and able to access to 2 big super markets. Kirk led us to use kitchen so we have made some meals during our stay.
Kirk and his family was always kind and warming. Thank you for letting us to stay your place! Love to come back to Berlin.
