What Our Clients Say
WARM STAY
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!

GREAT APARTMENT FOR SHORT STAY IN LUXEMBURG
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 GOOD APARTMENT
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.

WE LIKED ABSOLUTELY EVERYTHING
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.

WE WILL COME BACK
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.

ROOFTOP TERRACE

EVERYTHING TO YOUR BEST SATISFACTION
The service was excellent. The location was perfect. 10 minutes from the city center. Everything was to our complete satisfaction.

CLEAN, COMFORTABLE, VERY MODERN HOTEL
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.

FIRST RATE
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.

MEMORABLE STAY FULL OF INSPIRATION
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 FELT VERY MUCH AT HOME
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.

BUSINESS TRIP
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.
