Just as a gentle information and heads up. As President Putin will be visiting, the Police advises the public that there will be some streets blocked for a couple of minutes (hours) between Senningerberg/Aeroport and the city whenever he passes the street.
Its mostly when he arrives on Thursday around lunch time and when he leaves around 19h Therefore watch out that you might be stuck in traffic. The Police will avoid major blockages, but you know how Luxembourg works, if they block one street, there is chaos everywhere. 700 Policemen will ensure security while he is here.
So good luck, and for those who can cope with German, here is an article of the "Wort" http://www.wort.lu/articles/5907308.html about it
