Norbert is just great. He was very friendly and helpful from the start. The place is also amazing, it has all the amenities you need, including a personal hairdryer, lots of towels, shampoo, etc. The bed, the pillows are very comfortable. Norbert also allows you to use his guest Netflix account, which was so great since it wouldn't have been possible for us to watch German TV since we don't know the language. Norbert didn't impose, we met in 4 days just a couple of times in the hall and he asked us if we like Berlin. Also, his cat is very cute and fluffy. 😄 Thank you, Norbert, for an amazing stay.
