If you use “3701 San Martin Dr. “ address, your GPS may tell you “ You have arrived at your destination” in the middle of the street in front of three trees (Figure 1).
The Bloomberg building is behind those trees but you will need to climb a set of steps to access the entrance of the building. To find the Mueller Upper Deck parking lot, try to search “ROTC building, Johns Hopkins, Baltimore” in Google Map (Figure 2).
That will take you to the road lead to the Mueller Parking lot. Take the turnoff indicating “North Visitor Lot” and “ROTC building” from San Martin Drive (red star in figure 2) and follow that road, pass ROTC building on the left, you will reach the gate of Mueller Parking lot (Figure 3).
After parking your car, walk toward the building at the end of the Parking lot (Figure 4), follow the concrete path on your left, you will see a double glass door (Figure 5) that lead you inside the building.
