We booked Niels' apartment with very short notice and were lucky that he had a vacancy. Niels was very accommodating with our arrival time and warmly greeted us at the apartment. He instantly made us feel at home. We totally enjoyed our three nights at his place. We found the apartment exactly as described and pictured, clean, sunny, modern, and homely. The location at Singel is superb; everything including the train station is in walking distance.
