Prague is the Capital. It is a famous city all around the world for its historical monuments and unique atmosphere. Being only about 350 kilometres far from the place where you stay, Ostrava, it is really easy to go there just for a weekend, or even one-day trip. It is especially beautiful before Christmas time when the streets are decorated and there are Christmas markets on the squares.
It is hard to say something general about Czech people, there is no real stereotype as with the careless Spanish or precise Scandinavian. And it is very important to differ between the two generations - older and younger, the older one being not too much open-minded and quite conservative, maybe also reserved to foreigners, whilst the younger generation is friendly and willing to help, also often inclined to be interested in other cultures.
What you might find useful is the information about prices here. Compared to many other European countries, the Czech Republic is quite cheap place. For one euro you can buy a loaf of bread or a beer in a pub. Regarding brand clothes, that is, on the other hand, more expensive than in London for example.
Regarding transportation, there are buses and trains running throughout the country and all of them, together with the public transport of all the cities, towns and villages, are to be found at IDOS website which is widely used and reliable.
As for climate, we always warn our incoming students, especially those from the South, about the winters we get here. Sometimes the temperature falls bellow minus 20 degrees centigrade. Therefore, whether you are arriving in September or in February, be sure you take some warm clothes with you, because the frosts usually hit between december and february.
Unfortunately, not too many people here speak English well, or even speak English. As the Czech Language is very difficult to learn, it might be more useful for you only to learn the phrases you need for the purposes of one or two semesters you spend here.
