Brussels Airbnb in numbers: the 2026 study of 12,325 nights

Study published 5 August 2026 — Sabimmo internal data: 4,197 accepted bookings across 52 managed Brussels properties, check-outs from 1 August 2025 to 31 July 2026. Full methodology at the bottom. Next edition: 2027.

Over the past twelve months in Brussels, a professionally managed short-term rental averaged 75.9% occupancy, €101.55 per night, with guests booking 33 days ahead for 3-night stays (median). Here is what 12,325 sold nights teach about the Brussels market — seasonality, neighbourhoods, platforms.

The 6 numbers to remember

• 75.9% average occupancy over 12 months (peaking at 87.4% in October, dipping to 68.4% in January).
• €101.55 average daily rate (ADR) — topping at €118.59 in December (Christmas markets, holidays).
• 3-night median stay (2.94 average) — Brussels is a city-trip and business destination.
• 33 days median booking lead time (42.9 days on average).
• 68% of bookings come from Airbnb, 29% from Booking.com — and Airbnb carries 78% of nights. Being on both platforms is not optional.
• €108.73 ADR in central Brussels, versus €90.41 in Ixelles and €86.52 in Saint-Gilles.

Seasonality month by month

Two takeaways: the Brussels autumn (September-November) is the real high season for occupancy — driven by conferences, EU institutions and city tourism — while December maximises price rather than volume. January-February are the trough to optimise (longer stays, adjusted rates).

Where do nights sell at the highest rate?

The city centre commands roughly a +20% ADR premium over Ixelles and Saint-Gilles — which compensate with solid demand and often larger units. The right math is net revenue per property, not headline price.

Platforms: who brings what

Across 4197 bookings: Airbnb 2834 (68%), Booking.com 1209 (29%), direct and others 154. Airbnb stays run longer (3.4 nights on average vs 2.0 on Booking), hence its 78% share of nights.

Methodology (and its limits)

Data: all accepted bookings with a check-out between 01/08/2025 and 31/07/2026 across Sabimmo-managed Brussels properties (52 active at period end; the portfolio grew from 34 to 52 units during the year, which mechanically weighs on occupancy in onboarding months). ADR = accommodation revenue excluding cleaning fees and taxes ÷ nights. Occupancy = nights sold ÷ (active properties that month × days in month) — a property counts as "active" in a month if it records at least one night. This is a professionally managed portfolio: whole-market Brussels averages (including occasional hosts) are likely lower.
