First of all: Antwerp is a fantastic city, and this loft is ideally located in what I consider to be the best part of town. Equally, the loft has plenty of space (living space and bedrooms) and has great views over the river Scheldt. However, there are two basics missing to make this a livable holiday home: maintenance and cleanliness. I would not recommend staying here unless there is a major change on these two fronts. Also I personally felt access security was not taken seriously.
From a maintenance perspective, a countless number of items are broken/not working. Just a few examples: less than half of window shutters open (mechanism broken), most window handles as you pull them fall off, the floor has holes in the wood and countless nails are sticking out, there are holes in the wall in the living room, the sofa is old and badly stained, the stove in the kitchen has 2 out of 5 plates working, the oven does not seem to work at all, many standing lamps are missing light bulbs, on of the taps in the master bathroom is dripping, the fridge is of very bad quality, etc.
Also the loft is marketed to have AC, but on arrival it proved to be one very old AC unit for the whole loft which as per the owner had been out of service for a long time.
Something structural that would be hard to change is the elevator, which fits maximum 2 adults or 1 adult and one suitcase - which makes for countless trips up and down with people, luggage, shopping, etc.
From a cleanliness perspective, the loft was simply dirty. Surfaces badly cleaned, same for the appliances, dust and hair on the floor, piles of dirt under the beds. Duvets and pillows are stained. This kind of place when used for rental needs serious and professional cleaning, not a low cost cleaning lady who is clearly unmotivated and loudly complaining.
Finally on the security point, access is through a code at the front door of the building, and then a code for the lift which arrives straight in the loft without an additional door. Whoever has the code comes straight into the loft. The first day, our code was shared by accident with other tenants in the building so they showed up unannounced in the apartment. But also the cleaning lady (who was apparently temporary) has the code and comes in and out unannounced straight into the living space.
In short, the place has a lot of potential, but in its current state will not make for a pleasant stay - do not go unless the items above are addressed through a structural refurbishment.
