Norbert's apartment is very stylish, light and bright and bigger than the photos suggest. There are a lot of steps up to his flat as it's the top floor but it's not that bad and totally worth it. The surrounding courtyard is really peaceful and it's nice to enjoy a coffee on the balcony in the morning and listen to the birds. The location is great with very good u-Bahn links into the surrounding districts.
Norbert is a wonderful host with a keen eye for detail and a pleasant and helpful demeanour. I highly recommend a stay with him and at his lovely apartment.
