Can anyone recommend some decent websites for searching for apartments in Prague? The most I come across with are highly-expensive luxury flats for short-term. I am looking for a modest flat with long-term stay. Thanks in advance for your help!
Unfortunately I cannot recommend you website. I can only give one more tip to extent your possibilities. If you don´t have to live in Prague, you can try to find an apartment outside Prague with good transport connection to Prague (e.g. Kralupy nad Vltavou). I don´t think there is a difference to travel 20-25 minutes by bus or subway or train. Rent will be cheaper, but of course there will be additional fee for a transportation. For all of that I think you will pay less than living in a distant city quarter in Prague.
