It's quite different away from the capital. I sometimes stay in a small town in Moravia which is the Eastern side of CZ, Prague is capital of Bohemia on Western side. It's very Czech with little English spoken. Population is about 100% indigenous Czech, not the mix we're used to. Crime is very low and everywhere is safe, day or night. It's a quiet backwater, and even the cities in the area are liveable and not hectic. They're quite relaxed without the consumerism b0II0x that obsesses Brits. Their culture is important to them, and manners are a big thing. They're quite friendly to Brits, much more than The French for example. It's a traditional country, bit like stepping back several decades. Most Czechs in cities live in flats, but outside cities, houses often have land where people grow things and keep a few animals. The roads are good, but not busy. Not potholes everywhere like here. Only bad jams are in Prague. Czechs often have a job for life, and whether you're a barman, waiter, tram driver or railway guard, they tend to take a pride in their job and appearence. It's their profession, not just a temp job filling in and they take it seriously.
Food is ok, but quite meat based and can be a bit heavy. Excellent value though, and big portions. Beer is some of the best in world (lager, but not chemical). There are 100s of breweries big and small, and out of tourist areas in Prague it's usually less than £1 pint/.5 litre. Pub culture is big and beer is everywhere. It's cheaper than mineral water where you can buy a .5 litre bottle in a supermarket for 50p. Pubs are busy and thriving, like ours were 40 years ago. Very cheap to live there. Friend rents a small flat and pays £175 pm and only other bill is leccy at £15 pm. No rates to pay. People in UK don't know how much they're being screwed.
The railways aren't high speed, and rolling stock is often old which is good because they still have seperate compartments in carriages. The trains aren't busy like ours and I often get a compartment to myself. Four hour journey is about £10, first class £20. Train travel is relaxing rolling through the countryside and complete opposite of the overcrowded, over priced trains we suffer here.
Wouldn't say that Czech countryside is as picturesque as say France, etc. But it's nice, quiet and has plenty of old and interesting places to visit. Plenty of historic towns if you want that. It's just a very civilised place where people have their priorities right and all very affordable.
