PERFECT FOR OKTOBERFEST!
First off, Christoph was the best host anyone could ever ask for! Once we booked his place, he sent extremely detailed info regarding transportation, check-in, and recommendations on places to eat. Christoph was also great at making sure we had everything we needed and was easy to get a hold of. He even had beer waiting for us when we checked-in!
We stayed at Christoph's place for 2 nights for Oktoberfest and don't think we can find another place that beats Christoph's place. It was less than a 5 minute walk to Theresienwiese - you can literally see Oktoberfest from the door.
The apartment itself was very modern and clean. It came equipped with everything you could possibly need: Projector & projector screen, tablet w/ Netflix readily available, bluetooth speakers, extra airbeds/mattresses, lots of towels, washer/dryer, and so much more.
I highly recommend this place, even if you aren't there for Oktoberfest. It's centrally located and the train station is about a 1 minute walk. Would definitely stay at Christoph's place again!
