If you decide to stay longer in Prague then it is a good idea to look for an apartment. Look for ads in newspapers, contact real estate agencies and special agencies offering serviced apartments for long term rentals. You should keep in mind location, transport costs and how long you wish to stay when choosing somewhere to live. A furnished apartment with room, bathroom, living room and kitchen usually costs around 12.000CZK a month outside of the city centre. If you want to live in the centre then you will probably have to pay double this, around 25.000CZK. With serviced apartments you can stay for a shorter term, based on daily, weekly or monthly rates. If you wish to rent an apartment from a real estate agency then you will need to sign for a lease of at least for 3 or 6 months and pay an agency fee (usually one months rent), plus 1 or 2 months deposit. If renting from a private person you will only need to pay a deposit. If you are staying for at least three months then this would be the best option as it is much cheaper, prices will be around 30 to 40 percent lower compared to staying in serviced sort term apartments. For long term rentals try PragueHome.com or Spolubydlici.cz
Students: There is now a reliable housing agency in Prague which can find centrally-located apartments at reasonable cost. Students are advised to share the cost of the apartment with two or three roommates. No long-term lease needs to be signed. For students who are interested in this option, please consult the agency websites:

Want to stay really cheap in Czech Republic? There are some ways how to stay really cheap. First recommendation is getting as much far as possible from Prague to smaller towns and villages. For Example 2 Bedroom apartment in a small town where is a high unemployment rate can cost you just 150$ a month. That's huge difference compare to staying in core centre of Prague where you can expect to pay up 10x times more for same apartment. Second option is finding so called "UBYTOVNY", they're kind of HOSTELS with two exceptions. They generally carter to poor ones (some locals plus many from Eastern Europe) and they're rented on monthly basis. One month can cost you anything form 2500CZK to 8000CZK (from 100$ to 300$).
