Mack Cali Realty : With Phase Two of Renovation Complete, Dynamic New Lifestyle is on Full Display at Crystal House in Arlington

Luxury Apartment Community in Crystal City Opens New Collection of Amenities,

including Two Rooftop Decks and an Olympic-Size Swimming Pool

ARLINGTON, Va. (Sept. 14, 2017) - Roseland Residential Trust, a subsidiary of Mack-Cali Realty Corporation (NYSE: CLI), today announced the completion of the second phase of the comprehensive renovation of the historic Crystal House community. Composed of 825 studio, one-, two-, and three-bedroom apartments, Crystal House, is located in Arlington's flourishing Crystal City neighborhood.

Roseland, an owner and developer of innovative multifamily communities throughout the Northeast, purchased Crystal House in 2013, and, in response to the strong demand in the Washington, D.C. metro area for spacious luxury apartments in transit-oriented neighborhoods, embarked on a plan to upgrade the community to the high standards of today's discerning renter

In the first phase of the renovation, Roseland reinvented many of the apartments at Crystal House, incorporating high-end features such as spa-inspired bathroom finishes, stainless steel appliances, granite countertops, and in-unit washer/dryers. In the latest phase, Roseland achieved the next step in the dramatic overhaul of the community's two buildings with the addition of the following upscale amenity spaces:

• Two rooftop sky decks with lounges and billiard tables
• Rooftop grilling and dining areas
• Penthouse fitness center with yoga studio
• Olympic-size swimming pool with cabanas and sun shelf
• Well-appointed new lobbies with Wi-Fi
• New clubroom with table games and gathering areas
• Conference room and cyber lounge
• Sleek new elevator lobbies
• Newly landscaped courtyard

'We've infused Crystal House with contemporary finishes and aspirational lifestyle components that exceed what's offered even at some of the area's newly constructed luxury communities - few of which offer nearly as much living space,' said Dennis Skarda, Director of Operations at Crystal House. 'For the large number of renters in search of the extremely rare combination of luxury, space and quick access to mass transit, Crystal House presents an unparalleled opportunity.'

Located at 1900 S. Eads Street in the heart of Crystal City - just steps from the Crystal City Metro station, Pentagon City, Reagan National Airport, as well as the bustling retail and restaurants of 23rd Street - Crystal House is in the heart of one of the most desirable transit-oriented locales in the D.C. region. Built in 1965, Crystal House was a cornerstone of the first planned developments of Crystal City, and the neighborhood derived its name from the apartment community and the large crystal chandelier that once graced its lobby.

'Thanks to its proximity to the Metro stop, and a growing retail, dining and entertainment scene, Crystal City has evolved into one of the most sought-after residential neighborhoods in the greater D.C. region,' Skarda said. 'Just as the neighborhood has undergone a renaissance, Crystal House has been reimagined. It's an exciting time for both the neighborhood and the community.'
