Thank you. We had such troubles arriving thanks to BA but Heinz was in contact throughout and made arrangements for a very late pick up of a key.
The apartment is very big and clean and very well positioned in central Berlin.
The u bahn is close as is unter den linden. 5 minute walk to Brandenburger Tor.
The office was helpful and concerned to help us with our lost luggage.
I would recommend this apartment unreservedly.
