Property Description

Spacious, light and bright co-op condo with great architectural detail in an elegant Art- Deco building built in 1927. Elevators whisk one to the 4th floor where one enters this charming unit through a generous hall with enormous amount of closet space leading to a large living room with decorative fireplace, beamed ceiling, ample space for a home office and multiple windows over looking unique San Francisco outlooks. A pleasing kitchen with stainless steel appliances, granite counters and a good sized dining area, an updated bath and a large bedroom with ample closet space is also accessible from the central hall. This well run and well maintained building has an in-house manager, a beautiful garden providing a welcome city refuge and a bike storage area. 630 Mason is within stone's throw of Union Square and Nob Hill and steps away from our theater district and some of the best and newest shopping, bars and restaurants that the City offers. A great pied a terre or City Home.
