The apartment is a little gem in the city. Very cosy, neat, and quiet. Nice architecture, and a classic-Antwerp duplex layout. It has a great location in he heart of town.
Sven is also a great host. There's a lot of attention to detail: dedicated guides, tips for restaurants, bars, ... and little touches such as Christmas decoration and a small bottle of champagne when I went there during the holidays. I'd be more than happy to stay there again.
