We stayed 5 nights. The apt is brand new, super clean, confortable, with a fantastic shower, flat TV with international channels. Best of all the confortable bed in which sleep better than well. No noises were heard at night. We didn't use the kitchen, although it was fully equiped with new fridge, dishwasher etc. The apartament is perfectly located, next to nordbahnhof S Bahn and trams. If you like to walk you could be in Alexander platz in 30 min, or at Friedrichst in less time. You have restaurant and bars to choose around. The check in and check out was smooth, they were waiting for us at the apartment at our arrival to show us how it worked everything, and came to pick up the keys when leaving, at the time agreed, and Moritz was easily reachable through the airbnb email application during our stay in Berlin. We would recomend it for sure.
