Moritz's place was great! I was greeted by Bohdanna as Moritz was away. She was very helpful and mentioned where the closest supermarket was and where the subway station was. She maintained communication throughout my stay and even Moritz messaged me while he was on a trip.
The location was great as the subway was just behind the building and the tram stop was out there as well. It's a gated building so you need a key to get in and out, so I felt very safe. I walked everywhere and it took me about 20-25 mins to get to the city centre.
The apartment was very clean and is exactly as the pictures depict it to be. I washed my clothes there and they had a rack to hang them, which was awesome. The best part for me was the bed. The mattress is memory foam and the pillows are down filled. I slept very well each night I was there!
I would definitely recommend Moritz's place to anyone visiting Berlin.
