Het Ballonnetje Coffeeshop is located on Roetersstraat, just behind the University of Amsterdam. It is on the east side of the city, in a neighborhood know as the Plantage. This is one of Amsterdam’s “green neighborhoods”. It is noted for its lush parks, including the beautiful botanical gardens (Hortus Botanics). The Artis Royal Zoo (Natura Artis Magistra) is also found here, which is one of the oldest zoos in mainland Europe. This section of the city is slightly outside of the city center, and the pace seems just a bit more relaxed here. Given its proximity to the University, it is also a noticeably youthful neighborhood, with a high density of students.
