This is an absolute STEAL. Truly, you won't find better value anywhere else. The private residence is located in the Conrad Hotel and it's much bigger than it looks! It's twice the size of the King rooms I book at the Ritz and a fraction of the cost. Huge tub, wonderful shower, convenient kitchenette, balcony with a tiny ocean view (mostly a pool view), comfortable king bed, two TVs, a desk, and a big couch. I didn't want to leave!
The amenities are great - beach towels, bikes, pool, hot tub, gym, pool bar, and awesome restaurant (Takato). Sure you have to pay the amenity fees but that should be a given since the unit is located in a hotel. Highly recommend going to Mancora, it's one of the only restaurants that isn't a tourist destination and it's amazing.
The unit is located two floors above the pool and hot tub which means a LOT of screaming kids, morning and night. You can't hear the noise when the doors are shut, but I wanted to mention it in case you're looking for a quiet balcony experience.
My only word of caution is if anything breaks, there seems to be a disconnect between the hotel and the owner. Neither of our TV remotes worked so I called the front desk, and they explained that since the unit is a private residence, the owner would have to put in a request. When I contacted the owner, I was quickly dismissed and told that the unit was sold to the hotel and it was not their responsibility. The owner does not seem to want any kind of communication, but it's a minor detail and I had a wonderful time aside from the screaming kids and broken tv remotes. I would stay here again in a heartbeat! Can't recommend it enough.
