Perhaps the most surprising part of your service was after the contract had been signed. Other agents would have been long gone, but you followed up with me, to make sure I was happy. Not just satisfied, but happy! You even came to my new apartment, and saw things, made some changes, that I might never have thought of, just to ensure my happiness. All I can say is: WOW.

Dear Sonar team,

Our first night in the apartment was splendid and we even cooked! Thanks again for all of your assistance and please let us know when is a good night to take you and Marja out. You went way above the call of duty and we do want to thank you.
