Belair is defined by its unique duality—a tranquil, tree-lined village that sits just moments away from Luxembourg’s vibrant core. Enjoy the independence of a private home with our Invisible Service model: we handle the cleaning, linens, and maintenance, so you can focus entirely on your mission.
You are positioned in the safe, prestigious Diplomatic Quarter. Forget the morning traffic—your office is just a short walk away through the park:
10 min walk to Boulevard Royal (Financial District) via Parc de Monterey.
12 min walk to Place de l’Étoile (Direct Tram to Kirchberg & Airport).
12 min walk to Hamilius (City Center).
Streamline your relocation process with flexible leases, VAT-compliant billing, and our signature “Invisible Service.” We offer dedicated account management for embassies and multinational teams.
Belair is preferred by locals for a reason. After a busy day at the office, you return to a sophisticated “village” atmosphere. Enjoy fresh croissants from the nearby Oberweis, casual Italian dining on the weekends, or a morning run in Parc de Merl. It offers the perfect work-life balance: cosmopolitan connections by day, village tranquility by night.

I recently travelled to LUX for 9 days for a business trip. The location was great, close to the supermarket and restaurants, and it is just a 10 to 15 min walk to the city center where bus station is handy. Walking through the park every day is fantastic!

We visited friends in Luxemburg and stayed at ApartHotel Belair. Really good standard and silent. All you need when you have a hectic week-end with a lot of plans. Warmly recommend!

Very clean and functional establishment. The staff is very welcoming and friendly. I have no complaints about the amenities and service. I stayed there for a business trip for two weeks and was very satisfied with the services. I’m returning soon for three weeks because I was so satisfied.

I highly recommend this establishment for all types of trips, but especially for business travelers who will appreciate the peace and quiet, the amenities, and the convenience.

Everything. We absolutely loved everything. Excellent location: a 15-minute walk and you’re right in the center. Very spacious room. The reception staff was very friendly and spoke decent Spanish, which my wife appreciated.

After living in Luxembourg for five years, we always look for hotels close to the city center when we visit. We hadn’t heard of this one before and were very impressed. We had what was probably the largest room at about 45m². Very convenient when traveling with a small child.

The rooms have a kitchen with a two-burner stove, refrigerator, and microwave.

The service was excellent. The location was perfect. 10 minutes from the city center. Everything was to our complete satisfaction.

From St. Marienkirchen
Excellent (and quiet) location, a few minutes walk from the old city. The apartments were serviced with every facility required for the independent traveller – fully equiped kitchen, VCR, electric iron, etc.

Key Inn Apartments are first rate, could not have asked for a more comfortable, modern and spacious room. Would not stay anywhere else when visting Luxembourg, this place was fantastic. Thank you.

This hotel is definitely an interesting place with a great location (Belair is at walking distance to city center). We spent one romantic weekend with my girlfriend and this was really the best we could ever find.

I spent three weeks at Key Inn and felt very much at home. The apartments are spacious with separate living and sleeping areas. The facilities are excellent with coffee machine, plasma tv, dishwasher, fridge and induction hob all available in the apartment.

The standard prices are a bit too high, but if you go for a business trip, you won’t regret it. You can organize your meetings, because the furniture is ultra modern.

Beautiful, spacious, clean and stylish studio. Room is very well maintained and offers all a frequent traveller could require.

Each Key Inn location serves a different lifestyle. If Belair’s diplomatic quiet isn’t the right fit, explore our other strategic districts to match your specific business or family needs.
The Business & Social Hub. Located just steps from the Glacis and a short commute to Kirchberg. Limpertsberg is the preferred choice for dynamic professionals who want to be close to the financial center, international schools, and the city’s best nightlife.
The Green Retreat. Ideal for families and long-term residents. Enjoy spacious living with direct access to Luxembourg’s most beautiful park. It offers a peaceful residential atmosphere with larger floor plans and easy highway access.
