Heide's place is wonderful. Very clean with a lot of extras which make it seem like home, such as plenty of towels, blankets, and hangers, CDs, books, etc. Heide rents her place frequently and makes your stay very easy. She provides a booklet of information about her flat and the neighborhood. We never met Heide in person, but she had her neighbor coordinate keys. The area is a clean, working class Serbian neighborhood with plenty of markets and restaurants in walking distance.
