Went here with a friend as a spontaneous Sobe weekend. Don't be scared by the adjective "boutique." We loved the decor, the location is unbeatable (next door to SLS and two blocks from Lincoln Street). It is right on the water.
Our room was in the 160s on the first floor - did not have an ocean view but there are rooms that do. Our room was small - anymore than one large suitcase and we would have been out of comfortable room. The bed was very cozy, clean and neat. The bathroom door didn't close quite right, though, and we would have to pull hard to get it to shut completely.
Late check out is an option but you have to request it, probably before 8pm or 9pm the night before. The free wine was a plus by the pool, though my taste buds did not care for the red.
Concierge was very helpful in securing us a reservation at a DYNAMITE restaurant Saturday at 9:15pm. They also arranged for our transportation. It was well received.
The only real complaint I have is with the valet, and only toward the end. We asked to pull the car around to put our things in after we checked out Sunday at noon. Unfortunately, this time was very busy and we waited about an hour for our car to come up. The valet / bellhops were clearly more concerned about the guests coming in than going out, and I understand this. Just bear this in mind if you want to put your luggage in the car while you continue to enjoy the pool and amenities long after check out.
