I am just back from a conference in the Czech republic. After roaming around the countryside, in an area called "the Czech Paradise" conference attendees attended talks in a castle. But that is not what is shown here.
I stayed one night in the Hotel Paris in Prague, before catching a flight to the USA the next morning. It costs more that some other hotels in Prague but less than a nice big city hotel in an American city. It was fantastic! Great architecture and service. Quiet room even though you are in the heart of the city. the best mattresses. And they give you a postcard too! What a deal.
And Prague.... well I am definitely returning! I saw only a little of the city.
