Sunbeam is within Al-Bayan compound. It is not near Hamad Hospital though. However if you are coming from Hamad Hospital towards sports round-about, turn left (towards villagio mall). Skip first traffic lights (al-sadd) and take a U-Turn from second traffic lights. The second traffic lights crossing has 4 big advertising boards on all 4 corners (for DAMAC, Masraf Rayan, School sports day, Islamic Museum). Once you take U turn, keep in right lane, pass the Teyseer gas station and turn right on first lane, go 100 metre you will find a mosque on left side, just before mosque is the al-bayan compund. Go inside and sunbeam is on your right side, ask the guard on gate.

Hope it helps.
