After deciding on impulse to book a break in Luxembourg I was told "nobody" goes to Luxembourg ... so it was quite a relief just to find this guidebook even existed.
Don't be concerned that this is the only Luxembourg guide you can find, it is the one you want! Information on buses, shops, souvenirs, food and restaurants as well as attractions in Luxembourg city, and thankfully the description of my slightly quirky hotel captured its atmosphere accurately. The language annex was very useful too.
Thanks partly to the book, but mostly to the wonderful city, I had a marvellous time. After reading the chapters on the rest of country I did want to explore further, but I fell in love with the city and decided ... oh dear ... I'll have to come back next year. So I can't speak for the accuracy of those parts of the books, but I enjoyed reading them.
