A friend and I will be arriving at Berlin Tegel airport and we will need to get to our hotel: art’otel berlin mitte, by park plaza. I think the address is: Wallstrasse 70-73, Berlin D-10179, Germany. Could anyone advise what our travel options are? Also any tips to make our visit a good one? We already have an idea of things we want to see. Thanks for your help!

I’m working in a travel agency,in reservation counter,I’m looking for some applicable ways to attract passengers more and increase our sale and so on.
In one word I want to be the best counter in this agency,please let me know whatever comes to your mind.
thanks in advance.
