Hein, an artist and a thinker, lives in an unusual, suggestive loft, a former synagogue converted into a factory then turned into an apartment by Hein himself. The place is unique, as is the pied-à-terre that Hein rents. I was welcomed with a bottle of white wine and a long conversation on philosophical and existential topics. Isn't that the original spirit of Airbnb? Meeting people and exchange with them? I'll therefore give five stars to Hein and his beautiful studio, which is also very confortable, quiet, and perfectly located (close to a lively students' area with a wonderful movie theater, the Kriterion, the botanical garden, and lots of inexpensive, genuine restaurants, cafes, and bars).
