Five spacious bedrooms, three full baths (including a serene primary suite with soaking tub), and two half baths are spread across four grand floors.

The full finished basement adds even more versatility, perfect for a home gym, media room, office, or playroom. Just steps from acclaimed dining, boutiques, and cultural destinations, this home sits in a neighborhood shaped by William Penns original vision and celebrated today for its vibrant energy and architectural charm. 523 Fairmount Avenue is a unique opportunity to own a beautifully restored piece of Philadelphias past while enjoying the best of modern city living.
