Planning to stay at the Renaissance Salzburg Hotel Congress Center on Reward stay. It looks like it's very close to a train station.

Can someone help me with collecting with the following:
1. Does it have a Concierge Lounge (or Executive Lounge as they may call it in Europe)?
2. Is it close to city center and the tourist attraction areas? How close?
3. It says that it's 2 blocks from the train station. Is this like a main train station? We will be arriving into the "Salzburg Hbf, Austria" station. How close is it or do we have to connect via other trains or transportation methods?

Thank you.
