This isn’t Mitte - it’s really in the middle of Wedding (confirmed for me by two people who live in the neighborhood), but it’s still a great location and very close to trains and easy to use as a home base to get virtually anywhere in the city.
The apartment had everything I needed other than some cooking oil or enough coffee, but that was easy to fix with the supermarket nearby.
It smelled strongly of cologne but was very clean. It was nice to have a balcony.
