Micheal was there to welcome us as arranged and we had no issue getting to the apartment from the airport. He was very helpful in showing us around the apartment and in particular helped to show where all the sights were, local shops, pubs, restaurants, markets and also local public transport routes we could use. The apartment was clean and tidy, had everything we required and was spacious enough for 5 people. Location is good also with only a 40 minute walk to Alexanderplatz (10 mins in a car) and is withing walking distance off most of the major sights.
