It was a little hard to find at first but once you know where it is its only a 10 min walk into the centre of town (beware of the big hill though!). Normal enough hostel with a beautiful view on the sunny terrace out the back where you can get a few drinks or have a meal. Rooms were pretty basic; beds, toilet and shower. Staff were helpful and polite. Luxembourg is a great city ! Put it on your agenda!
Rooms were lovely and the whole building is done up really nice with a big bar and the guest kitchen was very handy if you didn't want to eat out all the time. It's only a 10 minute walk to the centre of town although the area between hostel and town was a bit dodgy, but you can rent bikes to get around so it was fine :)
