何方 is literary/classical Chinese. In modern speech, use 哪里 (nǎlǐ) or 哪儿 (nǎr) instead. 何方 appears in dramatic dialogue, period dramas, and the set phrase 何方神圣 (who is this person — said with attitude).
usage
The phrase 何方神圣 (héfāng shénshèng) literally means 'what place's deity' and is used sarcastically to ask 'who does this person think they are?' Very common in Chinese TV dramas.
