The Key Inn Appart Office provides apartment-style living in one of the nicest neighborhoods in the city. This makes it one of the more unique accommodations in Luxembourg City.

It is only a short distance from the Adolphe Bridge, Parc de Ville, Constitution Square, Grand Ducal Palace, and the many museums that fill the region. The Key Inn Appart Office is located at 42 rue Albert 1er, and is 5.1 miles from the Luxembourg-Findel Airport.

Although the style of the units vary, all apartments in the Key Inn Appart Office are equipped with modular furnishings, full-sized bathrooms with power shower, a fully equipped kitchen, high-speed Internet access, satellite TV, direct dial phone service, and housekeeping.

When staying at the Key Inn Appart Office visitors will have a home-like accommodation, but can also look forward to such facilities as the 24-hour front desk service, banqueting facilities, laundry and dry cleaning services, free daily breakfast service, a private terrace and garden area, a business service center, and free parking on the premises.
