Hotel itself is fine, staff seems untrained, not recommended for business meetings
The Argonaut is clean and modern, and the nautical theme works given the location on the Wharf, it's less like SpongeBob than their web site photos suggest.
The problem is with their staff and service. My company arranged a business meeting through the Argonaut, and the staff was inflexible in negotiating rates for a block of rooms. They made mistakes in booking people for rooms, specifically telling several guests there were no rooms in the reserved block when in fact there were.
Overall, their staff seems inexperienced and untrained. I noticed this at another Kimpton Hotel in NYC (Eventi). Examples at the Argonaut included friendly but not very helpful bell staff, you ask for a cab and they eventually call one. One of my colleagues had asked the concierge for a cab and was told she had to ask the bellman "because otherwise they won't get the tips." A concierge that won't help - I've never heard that one before.
Tip for Kimpton management: invest heavily in staff training to improve service. You have some nice properties, but are a far cry from the major leagues when it comes to creating positive customer experiences.
