We were in contact through whatsapp and we were welcomed exactly as plannen at the appartement. The appartment was very large (for 3 of us) and quite well equipped. Stefan helped us with a local restaurant, and it was even possible to leave our Luggage a little longer. The place is very well suited to cosy restaurants and easy with U-bahn (very close) to reach everything in the city. Yes there is a noisy street, but it really was no problem for sleeping. Very worth the money.
