As an Italian, I think I can intervene on this point.
There are many Orthodox Churches in Italy. Orthodoxy is growing through the conversion of Italians married to immigrants, but it must be said I know of full-Italian clergy in Italy, so definitely Italy is becoming "more Orthodox". The main reason might be the infiltration of RCism in Italy which is often looked at as a bad interference.
As for the churches, here's a list of main movements within the Orthodox in Italy:
The Archdiocese of Italy, under the omophorion of Archbishop Gennadios (Zervos), of the Patriarchate of Constantinople. It's legal see is in Venice.
The Russian Archdiocese of Western Europe, which has divided from the Patriarchate of Moscow and is now under the EP. It's legal see is in Florence.
The Patriarchate of Moscow, represented by the Diocese of Korsun, Decanate of Italy. The Decane is Archpriest Antonio Liotti, and its legal see is in Brindisi.
The Metropolia of Zagabria, Lubiana and Italy, under the Serbian Orthodox Church, under the omophorion of Metropolitan Jovan (Pavlovic).
The Diocese of Italy, under the Patriarchate of Romania. Its legal see is in Rome.
The Patriarchate of Bulgaria, whose legal see is in Rome.
The Autocephalous Church of Polland, entrusted to Fr Pietro Nazaruk, legal see in Sassari.
The Russian Orthodox Church Abroad, actually represented with only one community in Bari - the other pre-existent communities have passed to the Patriarchate of Moscow or the papovcy Old Believers.
The Greek Old Calendarists, not in communion with the EP or any other Patriarchate.
The Orthodox Church in Italy, whose see is in Ravenna. This church has his own Metropolitan but is in communion with the Ukrainian Church of Patriarch Filaret and with the Bulgarian Church of Metropolitan Innokenti of Sophia, but not with the EP.
There are no Antiochians in Italy. Our country has been literally (and positively, of course) invaded by Greeks, Romanians, Serbians, and recently Russians. Albanians would be present if it weren't that the communities of Albanians hadn't been absorbed in antiquity by the RC: there are in fact some Albanian Rite Catholic Churches in Souther Italy! I don't know anything of that Georgian Church you mentioned.
In Milan, there are five communities in communion with the EP:
The Greek Orthodox Church of the Annunciation to the Mother of God, under Archimandrite Timotheos Moschoupolos
The Orthodox Church of st. Anargiri, Cosma, Damian and Panteleimon, under Fr Nicola Ramaudo
The Orthodox Parish of st Serge and Seraphim, under Igumen Fr Dimitri (Fantini)
The Serbian Orthodox Parish, under Fr Dusan Tomic
The Romanian Orthodox Church of the Descent of the Holy Spirit, under Archpresbyter Traian Valdman.
You just have to pick and choose...
In Rome, there are too many parishes to list here. For anyone interested, try and give a look here: http://digilander.libero.it/ortodossia/Indirizzi.htm
This what I would call good service. I've been considering a little trip to Milan on August and I was going to start a new topic to ask whether there are any Orthodox parishes in Milan. It seems that there are several. Now the only problem is that I won't propably understand anything of the services because of language issues. Tongue
I live in Bergamo, not far from Milan (it takes 50 minutes by train). If you need some support, just ask... maybe I could help you. If you are coming in the last week of August, for example, I might even be at your disposal as a guide: just ask! Anyway, I read that you're a member of the Finnish Orthodox Church. Maybe a Russian Church might be of your interest? There's on in Bergamo, if you like (the one I'm attending
