Karstens apartment is close to the tube station, making it a great base for exploring Berlin. Karsten gave us useful directions to aid us to get from the airport. We were met by Natalie who showed us around and helped us settle in.
The apartment itself is spacious, clean and well presented. Its furnished in a retro style which worked for us!
The bed is large and comfortable, with fresh linen. The shower is instantly hot and powerful. We didn't use the kitchen to cook but can confirm it had what was needed to prepare basic meals.
All in all we were very pleased with our stay at Karstens place.
Great host, great place, great city!
