Great and friendly communication all the way through from Thomas and Angelika. The apartment was spotless clean and all ready at the agreed time. Check-in/out via key box was extremely convenient. Very, very nice apartment with a little balcony in a secure neighborhood with loads of cafes, restaurants and shops all around. We had all we needed for our 4 day stay. Supermarket literally just around the corner. Yes, it's on 4th floor with stairs, but it's good exercise :-) Located very close to M4 and M10 tram, which will take you to some mayor sites and ensures easy connection. The public transport in Berlin just works. Will highly recommend this apartment for a Berlin trip.
