Ville Haute
Staying in Ville Haute puts you minutes from the museum, with the panoramic lift connecting the upper town to Pfaffenthal below. Hotel Parc Beaux Arts is 40 m away, a 1-minute walk, and Hotel Vauban is 280 m away, a 4-minute walk, with breakfast, family rooms and free Wifi. Hotel Le Place d'Armes Relais & Châteaux, 360 m away, is a 5-minute walk, and Guillaume Suites is a 4-minute walk with family rooms and air conditioning.
Pfaffenthal
The museum's own quarter is residential and quiet after 8pm, so an evening here feels like having Luxembourg to yourself, and Ville Haute is a trivial lift ride up. Lago Welcome Palais, 100 m away, is a 1-minute walk with family rooms and free Wifi, and Lago Welcome Palais Suite, 30 m away, is also a 1-minute walk with free Wifi. Graace House Suites, 160 m away, a 2-minute walk, takes pets and has a kitchenette.
Grund
Grund, one gorge over, has the restaurants Pfaffenthal lacks, which suits anyone who wants dinner within reach after a day at the museum. Stylish Stay in Grund with Balcony & City Views is 290 m from the museum, a 4-minute walk, with a kitchen for meals in. From here the walk up to Ville Haute via the lift is trivial, and the train to Kirchberg via Pfaffenthal-Kirchberg station takes 3 minutes.
