Souk asiri is next to souk el deira the marble building if you go by taxi it.s easy if you drive go to Alfardan Buildind near gold souk coming from airport going to cheikh hamad road where all the banks are located after the swords, you pass the alfardan buildind, the next right turn is the way for both souk el asiri first than el deira it.s always crowded if you want to park you better go 8.30 morning or 4 o.clock. my opinion take a taxi.
