The website is in Czech, but you can guess your way around. For rental price list, click Pujcovna -> Lyze a snowboardy (cenik). There are 4 rental categories: weekend (viken celkem), a day during the weekend (viken na 1 den), all week (tyden celkem) and a non-weekend day (tyden na 1 den). You can either deposit in cash (vratná záloha) or by credit cards except Master Card. They charge double for deposit by credit cards.

The rental price is decent, plus the equipments are fairly new.

In addition to selling new merchandise, Harfa Sport has a medium-size underground bazaar of used skis, snowboards, shoes and snowing gears. The prices look reasonable to me. I would probably buy a snowboard there if they had my size.
