The Alexey

635 4 Avenue is praised for its prime location in South Slope, well-maintained, clean environment, and friendly, helpful staff, especially the doormen and maintenance team. Amenities like rooftop, gym, and a secure package room enhance tenant experience. However, multiple renters cite significant issues with HVAC units being outdated, noisy, and inefficient, leading to high utility costs and discomfort in heating/cooling. Hot water supply is frequently inadequate, and building insulation and noise isolation could be better. Management responsiveness varies, with some reporting poor communication and slow repairs. Rent stabilization and newer facilities attract tenants, but maintenance and management improvements are needed to retain residents.
