I stayed for one weekend for Oktoberfest and I loved the location of this apartment. The train station was very close and after two stops we would get to the Oktoberfest grounds. The English Garden was my favorite and it's just up the road from the apartment. The restaurants around the place were amazing as well.
When we arrived to the apartment Piet greeted us, showed us around the apartment, and gave us a few suggestions for our stay. He was very accommodating and let us check in a bit earlier since our flight arrived in the early morning. Also, the apartment was fully equiped with everything you may need such as food, toiletries, etc.
I would definitely consider Piet's dream flat again.
