I stayed for a month as I moved to Luxembourg for work and while I was looking for my definitive place to move to.
This apartment is great because the space is extremely well organized, and there is a small but fully functional kitchen. I cooked and ate at home every day and it was very practical even if not huge.
The location is great, very central close to many buses and close to the train station, and i found it perfect as I had to commute to work by train every day.
Lastly, if you need a fiscal invoice for your employer or your business trip, this property is owned by a company so they can issue you an actual fiscal invoice.
Highly recommended !
