Rainer and Nikola was very helpful in getting us to the loft. our train was delayed, and he was patient, buzzed us in, helped us with our bags, and showed us around the place. ryanair lives right next door, where he informed of us a lot of local spots. Nini e Pettirosso (pizza and pasta) was a great recommendation, and he also directed us towards the old airport, templehofer field. on a very hot day he came by with watermelon. on top of the amazing hospitality, it is also only a few blocks from both the s and u bahn (local transit).
