New York City ? If you’re looking for a Manhattan apartment, be prepared to shell out about $2,000 a month – unless, of course, you’d like a bedroom to go with it.

Studio apartments in New York’s most expensive borough went for an average of $1,995 a month last year, according to an analysis released Friday by Citi Habitats, a Manhattan rental brokerage firm. That’s up from $1,659 in 2002.

The average rent for a one-bedroom apartment shot up to $2,737, compared to $2,227 in 2002, and two-bedroom apartments climbed to $3,893, from $3,198 in 2002. Three-bedroom apartments saw the largest percentage increase: more than 36 percent, from $4,059 in 2002 to $5,534 last year.

The increase did nothing to decrease demand. The overall rental vacancy rate for Manhattan last year was less than 1 percent.
