520 North Central Avenue Heliport

It appears there might be a misunderstanding regarding the nature of "520 North Central Avenue Heliport (US-9209) in Glendale, US." Based on recent information, 520 North Central Avenue in Glendale, California, is primarily associated with a residential apartment complex known as Arista Glendale, which resulted from the adaptive reuse of an office building around 2022. This address is marketed for luxury apartment living, offering amenities like fitness centers, lounges, and business workspaces, not as a public-access heliport for travelers.

The code "US-9209" does not correspond to a public-use heliport with available traveler reviews. While there are numerous heliports across the US, many are private, often associated with hospitals for medical transport, and do not generate public traveler feedback or experiences similar to commercial airports or even dedicated private charter heliports. The only mention of a commercial heliport in Glendale is the Sunset-Glendale Heliport (55CN), which is a different facility located approximately one mile from downtown Los Angeles and serves for private use and charters to other locations.

Therefore, a summary of recent traveler reviews and experiences for "520 North Central Avenue Heliport (US-9209)" cannot be provided as there is no evidence of this location operating as a public travel heliport with accessible traveler feedback. The address is instead identified as a residential building, and the provided heliport code does not link to any public travel-oriented facility in the search results.
