"We were fortunate to hit the market at the right time," says John Mambrino, senior managing director of Studley, in a release. Mambrino, who represented Lukoil along with Studley managing director Nicholas Farmakis, adds that 1095 Sixth Ave. "represented the best option" out of a handful of well-located properties.

He notes that the property's location near Bryant Park and convenience to mass transit access access for Lukoil employees were strong draws. Adds Farmakis in the release, "The building itself has been impressively renovated, and the landlord is constructing Lukoil's space on the 33rd floor to its specifications." Lease terms were not disclosed; asking rents at the 1.3-million-square-foot office tower are in the high $60s per square foot.

Blackstone was represented in negotiations by the CB Richard Ellis duo of EVP Robert Stillman and first VP Zachary Freeman. Robert Nash and Keith Pollock of Schulte Roth & Zabel were the attorneys who acted on behalf of the ownership, while Daniel Weisz of Marans, Weisz & Newman provided legal counsel for Lukoil.
