The location of the apartment is excellent - very safe due to having plenty of embassies close by. It is easily accessible from Tegel airport by bus and the metro at Brandenburgen Tor is within easy walking distance. The apartment is rather basic, but then again clean and everything worked well. Only problem was the wifi - there is a router in the flat but it only worked on one day. For some reason it just failed to connect and there was not much we could do about it. We got the keys from an office close by, and they would have sent someone in to repair it, but as our stay was only 3 days, there was no need for this. The office arrangement was perfect and they were very friendly. There is a big food store close by and of course the Mall of Berlin with every shop you can think of. I can recommend this to parties of friends or families with children.
