My husband and I stayed at Karsten's place for a week. The loft was just as the pictures showed but felt much bigger because of the smart layout and high ceilings. There are also two large windows that let in a lot of light. The bed was very comfortable and everything was in working order. It is the perfect place for a couple or a single traveler.
Check-in/out and communication went smoothly and it was easy to find the apartment based on Karsten's instructions.
The stylish, urban vibe of the loft fit right in with the area. It is close to everything which was great for us because we did not bring a car. We were able to reach Karlsplatz and Marienplatz in 5 -10 minutes walking. Because it is central, you will hear sounds from the street but the apartment complex itself is quiet and felt safe.
I highly recommend Karsten's place if you plan to stay in Munich.
On a side note, there is a restaurant right next door you need to try if you do book this listing.
