WeWork is city's largest office tenant, but some landlords are wary

At the beginning of September, WeWork, the $20 billion provider of flexible workspace, was close to signing a lease at the city's tallest office tower.

The deal—to take about 200,000 square feet at 1 World Trade Center—would have made the eight-year-old company the city's largest office tenant, a milestone it wound up hitting recently through a separate deal. The company now rents 5.3 million square feet total.
