We've done a lot of trips to Palm Springs and have been to the usual suspects - Ace, Holiday House, Sparrows, etc. Dive is a fine boutique hotel, but that's exactly how i would rate it - it's fine. Staff was super nice, but there were clearly issues with training them (for instance, undercooked hard boiled eggs, thick and soupy coffee, etc). Things you should have no issue with if you're paying $500+ a night for a basic room. Service was slow at the pool which is a wasted opportunity for them to make money. We even were charged for an item from the mini bar (beer) that neither of us could even drink if wanted to (I am gluten intolerant and my wife is pregnant). The shower was not adjustable and was higher pressure, which actually kinda hurt our skin if it hit a sensitive spot. No big deal breakers - but little things like that are weird in a pricey spot.
Positives - super nice staff. Pool was great temp and the pool chairs and umbrellas were all great. Daybeds were awesome to lounge in. Staff was very nice (just slow). Room was very clean. I think this room/experience should have been $300-350 night. $500+ felt a little aggressive for this.
