We had mould on almost every wall, the walls were damaged, too. The floor and the cutlery were dirty - I don‘t know for what we had to pay the cleaning fee. It took Smartflats almost 24h hours for a response to our issue. After contacting Airbnb we luckily received a refund. The location was good - BUT NEVER AGAIN!
Excellent location near the Europen Commission and Consilium. Nice aparment, well equiped. Easy self check-in.
