how far is the airport away from berlin city centre and what is the transport like
Tegel you can take the bus to get into the city centre or take the bus to the S-bahn or U-bahn depending on where your hotel is. Schonefeld has trains that go directly to the city.
If you'd like to tell us which hotel you're staying at, and which airport you're arriving at, you will get a better idea of how long your trip will take you.
Come on, Alabastron - you're the expert, you should know! ;)
Who, me? :o) Sorry, my crystal ball appears to have disappeared. :o(
A nice Mercedes S class from mydriver.com makes for excellent transport, I use them a lot. Though they will need to know your arrival airport and hotel as well and cost a little more than a bus :)
Which airport, Denise?
