This is a terrific neighbourhood, full of old and new restaurants, pubs, shops. Henrik's place is perfectly situated: 5 mins to subway, supermarket etc. Berlin Visitor card is great value - getting the museum insel one also allows you to skip the ticket queues - huge plus on a rainy day. Flat is comfy and Henrik is very friendly and helpful. He kindly posted me on a book I'd left behind, at his own expense. Our only regret is that we didn't have two weeks instead of three days!
