Affinity Old Post Apartments in Baltimore: Converted Historic Building with Modern Finishes in Federal Hill
Affinity Old Post Apartments is a 147-unit residential building in Federal Hill that occupies the former U.S. Post Office sorting facility at 10 East Lombard Street. The property combines exposed brick, timber beams, and original architectural details from its 1920s construction with renovated units, stainless steel appliances, and climate control. It sits two blocks from the Inner Harbor and three blocks from the Federal Hill Park overlook, placing residents within walking distance of restaurants, retail, and waterfront access.
Unit types and floor plans
Affinity offers one-bedroom, two-bedroom, and three-bedroom floor plans. One-bedroom units range from approximately 650 to 750 square feet. Two-bedroom units run 950 to 1,100 square feet, and three-bedroom units reach 1,300 to 1,500 square feet. All units include in-unit washer and dryer, walk-in closets, quartz countertops, and stainless steel appliances. Floor-to-ceiling windows in corner units and higher floors capture water views and natural light; interior units on lower floors receive less direct sunlight. Several units retain wood beam ceilings and brick walls from the original structure, while others have been finished with drywall and painted surfaces.
Rental pricing and lease terms
Monthly rent for one-bedroom units runs from approximately $1,800 to $2,100, depending on floor level and window exposure. Two-bedroom units range from $2,400 to $3,000 per month. Three-bedroom units start at $3,200 and exceed $3,800 on higher floors or with superior views. Affinity requires a security deposit equal to one month's rent and conducts a credit check and income verification during the application process. Lease terms are typically 12 months; shorter leases may be available at a premium. Parking is available but not included in rent; covered and uncovered spaces lease separately at rates that should be confirmed directly, as they fluctuate seasonally.
How Affinity compares to other Federal Hill and Harbor options
Federal Hill has several other mid-rise apartment communities. The Promenade at Harbor Point, located one mile northeast along the waterfront, offers newer construction and building-wide amenities like a rooftop pool and fitness center but commands higher rents (typically $2,100 to $3,300 for one-bedrooms). Affinity's appeal lies in its character: tenants pay for historic architecture and walkability rather than resort-style amenities. Cross Keys, a mixed-use community in Roland Park about two miles northwest, provides more space and quieter surroundings but requires a car to reach dining and entertainment, making it suited to families prioritizing green space over urban convenience. Harbor East apartments like The Fitzgerald on Thames Street occupy newer construction within a similar price band to Affinity but lack the industrial-chic aesthetic and offer more uniform, corporate interiors. For renters drawn to exposed brick and original timber in a walkable waterfront neighborhood, Affinity's converted-warehouse identity differentiates it from purpose-built residential towers.
Building amenities and services
Affinity provides a fitness center, a resident lounge with kitchen facilities, bicycle storage, and package receiving. The building does not include a pool, rooftop terrace, or concierge service. Pet policy permits dogs and cats with a nonrefundable pet fee (amount to be confirmed); breed and weight restrictions may apply. The property manages its own maintenance and lease administration in-house.
Who this building suits and who it does not
Affinity appeals to renters who value neighborhood character, waterfront walkability, and in-unit laundry over extensive building amenities. Professionals working downtown or in the Harbor East office corridor benefit from proximity to the light rail and easy commutes. The exposed brick, timber ceilings, and corner window units attract tenants seeking distinctive interiors for the price point. Households requiring a dedicated rooftop lounge, concierge, or resort-style pool will find better fits in newer Harbor Point or Canton developments. Renters with noise sensitivity should request units away from Lombard Street, where traffic and weekend activity in Federal Hill can be audible on lower floors. Families with young children may find the urban setting and lack of building-wide recreational space limiting compared to suburban alternatives.
Application process and first lease steps
Prospective tenants schedule a tour through the leasing office or website. Tours typically last 20 minutes and cover available floor plans in the building; agents show finished model units and can discuss lease terms. After viewing, applicants submit an online application with proof of income (recent pay stubs or tax returns), identification, and authorization for a credit and background check. Approval usually takes 3 to 5 business days. Upon approval, tenants sign a lease, pay the security deposit and first month's rent, and receive keys and parking assignment information before move-in.
Hours, location, and logistics
The building leasing office is located at 10 East Lombard Street, Federal Hill. Office hours and phone availability should be confirmed directly, as staffing varies seasonally. Street parking is available on Lombard Street and surrounding blocks but fills quickly during evenings and weekends; covered and uncovered garage spaces lease separately. The light rail's Baltimorestation sits eight blocks west; the Inner Harbor Walk is two blocks southeast. Direct bus routes on Lombard Street serve downtown and Canton neighborhoods.
Affinity Old Post Apartments holds its position in Baltimore's rental market by converting a landmark building into walkable waterfront housing without erasing its industrial identity, making it a practical choice for renters who want Federal Hill's location and character rather than a blank-slate apartment tower.
