Our stay at the appartment was great. We didn't meet Henning, but there was a key pickup point on our way which made it very easy and if needed we could always reach our host using Whatsapp. The appartment was just like the pictures. Really cool place for us to relax before or after heading to the city. Another cool thing is the lively neighbourhood. A lot of nice bars & restaurants to hang out closeby, you should really check out Hennings reccomodations, we loved the places we visited. And if we needed to travel it was only a short walk to the closest subwaystation. We would definitely recommend this appartment.
