I have an office in Luxembourg and I've stayed at the Hostellerie du Grunewald a number of times. I've enjoyed every minute of my stays.

The main business of the hostellerie is their famous restaurant, and the entrance that is common to the hotel and the restaurant, while small, is rather grand.

The rooms are nice and stylish with an antique flavor, and while this is not a 5 star property (no A/C, usually something like a chipped mirror, etc.) I cannot think of a more elegant place for the money.

Service is wonderful, and breakfast is an absolute feast. A wonderful place to have either a romantic start of the day or an impressive early business meeting.
