Our family of four stayed at Nicolaj's place for 9 nights. It truly is a fantastic apartment and was equiped to meet all our needs. Upon arrival we found a very nice welcome gift. The apartment was spotless and clean all over. Nicolaj was not there when we arrived (or left..) but the key exchange was handled smoothly. As was all communication.
We would highly recommended staying at Nicolajs place for those wanting to explore Copenhagen. Almost everything within walking distance.
