Have lived here in a small 1 BR for over a year and am a big fan of the location (in lower Pac Heights near social spots and amenities like Mollie Stone's across the street as well as right by Alta Plaza) and management team. Neighbors are very friendly and I've never had any noise issues.
Two issues I've had are with critters (ants rear their heads during the winter as the building is old) and the building has had a few break-ins. Sometimes California St. can be noisy and each apartment has a radiator which can be noisy at times too.
Overall very happy with this building and apartment.
