Michael's apartment is very spacious, modern and immaculately clean. We hired a car from the airport and he has private parking which is a massive bonus. The kitchen is well equipped and there is an Aldi supermarket 10 minutes walk (2 mins drive) away.
It is a little way from the centre but the public transport system is excellent and a taxi is only 11 Euro. It was a fantastic base from which to explore the wonderful city of Berlin.
Michael made sure that the essentials were supplied and responded very quickly to any questions I had and gave us some great recommendations for restaurants.
