Wife and I went to UNICO for our first wedding anniversary in April, having been to other numerous AI resorts.
Beautiful resort, better than average food, terrible, impersonal customer service. Our hostess was worthless. Day one I told her the app wasn't working for room requests, room service, etc. Her response, "Hmm." Instead of her owning the problem and finding a solution, I took 30 minutes out of my trip on the phone with the hotel IT department getting the issue fixed. Frustrating. 2 of the days our hostess was completely unreachable. Just awful.
Poolside service was spotty at best, I regularly moved our umbrella and fetched new towels, even went to the bar to get our own drinks. We'd often go an hour without anyone stopping by to ask if we needed anything. Disappointing. Beach is unusable. Tons of stinky seaweed.
The hotel did nothing to help us memorialize our occasion. Nothing. We mentioned it during booking, pre arrival, when we made dinner reservations (side note: you have to make reservations if you want to eat at a reasonable hour. The reservations are made thru open table, and are clearly being abused). We would have been happy with just flowers in the room or a bottle of champagne, but they did nothing. So impersonal.
The next to the last day I took to their Facebook page (they post to social media multiple times daily) , and was finally able to get some attention. After that, the hotel made a decent attempt to correct what was an "oversight" but the trip was already a disappointment in our books.
If your budget is $500+ a night, you can do better than UNICO.
