Annex on 12Th has a 4.7 out of 5 rating from more than 100 resident reviews. Residents rate location (4.7) and management (4.6) highest and building quality (4.0) lowest.
Annex on 12th delivers a consistently positive resident experience centered on exceptional staff service, well-maintained facilities, and premium amenities in a prime location near the National Mall and Wharf. Residents praise responsive maintenance, professional leasing and concierge teams, and thoughtfully designed common spaces including a 24/7 gym, rooftop pool, and speakeasy. Minor concerns include soundproofing limitations in some units, elevated parking fees ($500/month), and occasional communication gaps during system transitions, though these issues affect a small portion of the resident base.
Management and leasing staff consistently receive praise for responsiveness, professionalism, and attentiveness to resident needs. The leasing team is noted for guiding prospective residents through the application process with patience and clarity, while office and concierge staff maintain a welcoming, service-oriented approach. A small number of reviews note that staff communication and efficiency could be improved, though this represents a minority perspective among the selected reviews.
Residents consistently praise the property's extensive and well-maintained amenities, including a 24/7 gym, rooftop pool, courtyard, speakeasy, and coffee café. The shared spaces are described as clean, luxuriously appointed, and thoughtfully designed. Location near metro stations, monuments, and museums is frequently highlighted as a major convenience. Maintenance and staff responsiveness to requests are noted as reliable and efficient.
The property offers exceptional walkability to major DC attractions including the National Mall, Wharf, and nearby metro access, making it highly convenient for residents without personal vehicles. Most residents praise the central location's proximity to restaurants, shops, and recreational areas, though one resident noted that proximity to train tracks creates noise concerns in some units. Transit access via the Smithsonian metro stop and nearby bus stops is consistently highlighted as a major location advantage.
The building features recently renovated spaces with high-quality finishes, thick walls providing good noise insulation, and well-maintained common areas including a gym and rooftop. Residents consistently praise the cleanliness and thoughtful design of the property. One resident noted external train noise as a location-specific concern, and another mentioned staff communication could be more efficient, but overall building condition and upkeep receive strong positive feedback.
Maintenance response is generally prompt, with most requests addressed within 24–72 hours and staff described as respectful and helpful. However, one resident experienced a no-show after scheduling a request through the portal, and several maintenance issues (sewer odor, plaster/paint damage, door touch-up, water temperature adjustment) remained unresolved. Overall satisfaction is high, though follow-through on scheduled work orders and communication consistency could be improved.
Annex on 12Th is somewhat walkable and somewhat bikeable, and transit is excellent.
