This collection of 100 private apartments is anchored in a main administrative lobby which is located in a building surrounded by shops, restaurants, and cafes. The lobby is an office-like affair, with drop ceilings, lime-green walls, brown carpeting, and some low-lying black leather couches. The buildings that house the apartments are scattered about the city center and range from stately 19th-century structures to stucco buildings built in the '70s, though the apartments themselves have a consistently contemporary aesthetic. While families constitute a large portion of the guests here, these are also a popular choice with younger groups of friends as the apartments are fairly close to a good nightlife district.

The main office of the company is situated just off one of the major shopping streets leading into the Grand Place, which is about a four-minute walk away. The area is characterized by cobblestone streets, small boutiques, and restaurants. The apartments are scattered around the city center in various buildings, and most are within a 10-minute walk of the management location and close to sights, restaurants, and shops. The central Brussels train station is about a 10-minute walk away and gives access to the airport in about a half hour, though there are lots of other bus options nearby the cluster of apartments that also allow travel to the airport with a transfer (each option about an hour).

The apartments, though individually styled, maintain a fairly consistent contemporary aesthetic. The spaces are filled with natural light and modern, spare decor. Linen-covered chairs and brushed-chrome bathroom fixtures are of the higher-end Ikea variety; kitchens often have a full chop-block wood counter surface. There are fun decorative touches in some of the apartments like hand-painted wall flourishes around a hanging clock. Bathrooms generally have walk-in showers, some with rainfall showerheads. All of the rooms have some version of a kitchen equipped with cooking and serving ware, a dishwasher, an electric kettle, a microwave, toaster, fridge, a four-burner electric stove, and coffeemaker. Street-facing rooms may receive unwanted noise in more popular nightlife areas.

The Opera Residence offers on-site parking, which many of the other apartment buildings do not, and which is a rarity in the center of town. All of the apartments have free Wi-Fi.
