eXchange is a currency exchange office, and the best place to change money in Prague.
It is located in the city centre, close to the Old Town Square, on the corner of Kaprova and Maiselova streets.
The rates at eXchange are better than those offered by the banks in Prague, and considerably better than most of the currency exchange booths.
Their building is secure, the staff are trustworthy and their exchange rates are consistent with daily movements in the international currency markets.
The currency in Prague is the Czech Crown (CZK).
eXchange will convert all major currencies into Czech Crowns, including Euros, Pounds Sterling, US Dollars, Japanese Yen, Canadian Dollars, Australian Dollars, Swiss Francs, Danish Krone, Norwegian Krone, Swedish Krona, the Zloty, Forint and Kuna. They accept these currencies in all denominations of notes.
It is worth noting that they prefer newer notes, without writing on them. For example, with Pounds Sterling the notes must not have marks on the Queen's head. It is probably worth taking a few spare notes in case any are rejected.
For larger cash amounts (changing into 100,000czk or more), eXchange offers VIP rates which are slightly better than their standard rates.
