This books gives the idea that Nicaragua is a dangerous place as the "rest of Central America", despite the fact that this country is among the 30 safest in the world.
It says be careful when you get down the bus, in an area which only happens to be the bus station from busses coming from Costa Rica, that indeed is a dangerous area, but any citi has red areas, well that is one.
But 95% of the tourist coming to Nicaragua come and land in different location, like the airport, and others which are more than safe.
Besides that, the book only shows one hostel in Nicaragua, which happens to be worst in town, there are at least 50 hostels, and B&B worth of mentioning, but seems like this hostel very badly rated in the country is paying advertising.
On the other hand there not many tourist books if you go to Nicaragua, that would be the only reason to buy it, but 60% of the information is inaccurate.
