Robert was so responsive, I'm inclined to think he sits at his laptop and waits for the guests , and prospective guests, to email him. He is a wonderful host, and gave great tips for places to eat and things to do. Getting from the airport to the room is always the worst part of traveling for me, and his directions made it 'turn-key'. He was the best host we have had. If Berlin in on your list, stay with Robert...and his best friend Jack is awesome, too! ... he never barked once, and loves apples for a treat.
