Originally I reserved a room in the Hotel Parc Plaza, but due to over booking I asked to take a suite in the Belair. The staff was nice and helpful; the breakfast was exactly what a person need, but the person in charge of the dining room wasn’t always there, therefore things were missing until she came back every 10 min.
The hotel is located barely 10 min walk from the town center, so it wasn’t a problem.
I can’t talk about the hotel price since I paid the price of the room I booked in hotel Parc Plaza which wasn’t expensive.

15 minute walk to the centre of Luxembourg. Rented the Veloh bikes – 5 minute ride to the centre square. Second stay at the Parc Belair – had a park view room this time; very quiet. Comfortable beds, clean room with soap, shower gel, mini sewing kit, mini bar fridge and safe. Excellent buffet breakfast. Nice to see that Tobias is still working at the front desk – he is most helpful and friendly! Free use of a computer with internet access one level below reception.

Easy to find driving in from Framce. Attrq tie lobby with welcome of fee and juice upon arrival. Parking inside for car. Rom ws small but well arranged with space for clothing to and in walk, in closet, good lighting in bathroom and a make up mirror. Balcony faced the lovely park. Easy walk to friends apartment and to down town thru the park. Comfortable bed. Good sleep. Breakfast was good and more than adequate. Pleasant staff. Would definitely use again for clientsor for myself.

For me this hotel scored a few very good points and a couple of poor ones:
Good location if you're driving and free parking. Room 110 had a comfy bed, good reading light, spotless bedlinen and bathroom, strong shower pressure, very good hairdryer and two very useful mirrors (magnifying and full lengh). Lunch-buffet was also quite good.
On the down side there were several black stains on the (light) carpet which made it unpleasant to walk bare feet and the TV was old and small.
The hotel was fully booked and most of the time there was only one person combining reception wih bar tasks, so guests had to wait. And rececption didn't answer the phone in the evening, probably too busy with the bar.
