My husband and I really enjoyed traveling around the north east of Slovakia using this book. Lucy Mallows has clearly done some thorough research even in the less travelled areas of the country. I was originally hesitant about buying the book as it's 3 years out of date (2007), but almost all of what she writes still holds (which cannot be said for many other guide books where information quickly loses validity/correctness) and we found ourselves relying on this book rather than another one we also had. That said, I would welcome a new edition post the Euro adoption and other recent developments in the country, which has changed so much over the last decades.
Her fondness of Slovakia and its people comes through very well in her writing, and it was obvious she enjoyed traveling around and doing her research. Particularly the inclusion of subtle cultural observations and her 'pozor!' notes adds real human value to the book, making the reading not only more interesting but also useful for the day-to-day encounters. I am myself Slovak so was able to appreciate and recognise many of them.
There are a few typos (especially in translations from English to Slovak), which I'm sure would disappear in a follow-up edition.
I'd happily use this book again traveling around Slovakia, also around the parts I am more familiar with, as it adds a lot of value even to the native reader, through its humour, passion, and detailed observations both of the country and its people.
