As you are driving on the road from Dominical to San Isidro (route 243), once you are nearing San Isidro you will arrive to an area calle El Hoyon. You will be passing the Coffee Mill of Coopeagri (Point A on the first Map below) on your left hand side, right before you pass a small bridge.
About 800 meters (half a mile) after Coffee Mill of Coopeagri there is an intersection (Point B on the first Map below). The main road continues to the right (Eastwards) and to the North another road starts (continuation of route 243). You will need to take the road going Northwards. Please be careful as this intersection is located at a turn of the main road and it makes it hard to see the vehicles coming on the main road in the opposite direction.
Follow route 243 until you see the Cemetery (Point 1 on the second Map below) on your left hand side.
After the end of the Cemetery, continue on route 243 for one more block. At the end of that block (Point 2 on the second Map below) turn right. You will then be on Avenue 2 heading East.
Go downhill for two blocks. At the end of the second block (Point 3 on the second Map below) you will reach 6th Street. Turn left and go on 6th Street (you will be heading North).
One you are on 6th Street you will be heading North. Towards the end of the block, you will see our building on the right hand side (Point 4 on the second Map below)
