Can you use a booking site like, Priceline or orbix to book your flight? You can get the hotel from the same place. I think they include maps of hotels....not sure I've only used them for flights. I think they do cars at the same time too. But in Europe the mass transportation is far better there than USA.

Never mind...I just saw your reply that your company has their own travel agent. That agent should be able to help you get a hotel close to where you need to be and provide maps( if they still do that in this day and age.
