Helene has a very beautiful sunny apartment in a quiet area near a metro stop. It's quite easy to reach anywhere in the city in 20 mins with the metro from here. The communication from her was perfect and the house had all the amenities one might need. Shops for buying daily stuff and restaurants are close by. Dr. Rainer was the sweetest person who welcomed us home and explained a lot of things beforehand. Thanks very much Dr. Rainer and Helene for a great stay.
