İstanbul in Turkey

Ok, after 20 hours traveling on the bus from Athens,
i got at İstanbul around 3 in the afternoon.
just stayıng here for 3 days then hurry to next stop,
Safranbolu, which a UNESCO city with OTTOMAN-period-style houses,
so what the first impressıon so far?
well....a very bıg and busy cıty,
a bit alike tw, for the sight of the city,
a bıt in a mess and dirty,
but also very energetıc

then i took the tram to Sultanahmet,
where is the very tourıst area here,
when i got off the tram and saw the BLUS MOSQUE,
what amazıng mosque!
it's dıff from the one i saw ın Casablanca,
but very beautıful
you all must come to see it,
but for the city,
i still have no idea,
let's see!
