Warning: This will be a rather vague post using outrageous assumptions.
ARIA Company, the most important location of them all in the whole of ARIA. However fictitious it may be, however impossible it seemed, it was still a requirement for me as an ARIA fan to investigate.
The first thing to find was the compass direction and the producers were ever so kind to include a windvane on the roof...except there is a discontinuity error.
ARIA Company faces East in the Animation
...but faces South in The Origination.
However, by piecing together visual and circumstancial evidence, I can quickly conclude that ARIA Company indeed faces South.
1. ARIA the Animation ep11, the three of them walk along the waterfront promonade westwards (with Symphony insert song playing).
2. ARIA the OVA ~ ARIETTA, Akari faces East from the Campanile when pointing out the direction of ARIA Company (can be deduced from ground lighting).
3. ARIA the Origination ep5, when the three split up at Himeya after practice, Akari is rowing East.
4. ARIA the Origination ep5.5, Akari approaches the fork of the southern promonade from the West (timestamp 02:20).
These evidence point to ARIA Company located somewhere between Himeya and the fork at East Castello on the southern promonade.
Looking Westwards from ARIA Company, we see the island of San Giogio Maggiore.
Looking West North West we see the outline of San Marco's Basilica and Campanile.
Amano art, view from ARIA Company facing south, with San Giorgio Maggiore seen in the South West, partially obscured by Aika.
But a semi-overhead view shows a promonade but with an unfamiliar looking outcrop, with ARIA Company built in front.
So while ARIA Company is actually pretty much fiction, one can more or less work out where it's "supposed" to be, the most likely being where the vaporetto stop is on the left hand side of the picture.

This in hindsight seems like a useless post - but the amount of overanalysis which went on in my head made me decide I had to get it all out.
