We missed our flight from Holland to Berlin because there was a train breakdown in Amsterdam , and Heike was very unhappy because she had to wait for us , even though we had contacted her as soon as possible to explain the situation . The next day , upon our arrival in Berlin , Heike was still very upset because she had to change her plans to wait for us , so the welcoming was not great . Heike has a nice apartment with a view of a lake . It is also well located near the Messe ; but Heike should be more understanding that unexpected travel incidents and delays are normal .
