The area can still be accessed with vehicles that have permits and a remote that opens it. Those are mostly:
1.) Delivery vehicles early in the morning (~6am) and late at night (~1am+) can come through to supply businesses in the closed area. They have a remote that opens the street blockages.
2.) If an oversized personal delivery needs to be made to a resident, it's possible to get a onetime permit that allows a truck to access the area.
3.) For people who have trouble walking the city has provided a few free electric powered golf carts/taxis that you can call and they come pick you up and deliver you to a destination (picture: https://www.visitljubljana.com/assets/Ljubljana-in-regija/Ka...). Since they're small and quiet they don't bother pedestrian traffic.
I wonder if Uber/Lyft could provide such service in US - they're already doing electric scooters, so why not electric transport for car-free areas?
Note that this is strictly old town center which has relatively small amount of residents but it's mostly dominated by businesses, hotels and airbnbs these days. The area is small enough to walk across in ~15minutes by foot. Near the edges there are underground parking garages so you can reach it via car (since public transport in the city isn't that great).
You can also move most, if not all, furniture that fits through a house’s door or elevator on a small electric van or even a (three-wheeled) bicycle.
Electric vans also could be the preferred method of supplying shops with goods. That need not be much more expensive if containers can be moved from larger vans onto such smaller vans at city boundaries.
If you have furniture that’s so large that you have to hoist it up and get it into the building through a window, you likely already need a permit to use the device that hoists up the furniture.
Can confirm, have moved king-sized mattresses, large dressers and cabinets, etc via a trailer on an ordinary bicycle. It’s really easy!
Where I’m from there’s a tradition in the bike community called a “bike move”. When you’re moving, you invite everybody to show up on a certain day with their trailers and cargo bikes. Everybody packs and moves you in a distributed manner! All you have to do is provide coffee and donuts in the morning and pizza and beer for after. Fun, community-building way to move.
If you strap the mattress to the box spring to stiffen the mattress you can set it on its edge and it won't sag. Then just set the box spring and the mattress on a flat bed bike trailer and you are good to go.
