Hi Junio, good luck on Monday.
The easiest way to get there is take the tube to Hounslow Central, 5 minute walk. Exit the station and turn right (under the bridge), walk 2 or 3 hundred yards, and you'll see Clovelly Road on the left which leads to the Civic Centre. It's the road with loads of purple signs.......you can't miss it. Go throughout the car park and it's the first building, entrance 'Lampton Park Conference Centre', with a small sign next to it saying 'Flight Training Europe'. It's very easy to find.
