Ok, I made a little map showing the hotel, the metro station and the rail terminus as the largest landmark in the neighbourhood. If it's on your left as you exit the metro - you've taken the right exit. The blue line is what I think is the shortest way to the hotel, taking in the account all the crossings you'll have to do.

When you open the map, zoom in for maximum detail and don't forget to switch it to Satellite or Hybrid mode.

Hope it helps
