Would not recommend this O:live whatsoever, from the initial check in to the check out. Was left waiting over 3+ hours for check in, further someone kicked my luggage at the front desk and reception/staff said nor did absolutely anything. Further, my review of the food at the hotel, is that it’s quite lackluster. The hotel attempts to portray luxury but reality its anything but it. I travel quite extensively, and have stayed at real 5+ ⭐️, and plenty of real 4 star hotels. This is 2 star hotel(similar to a holiday inn or Hampton inn) pretending to be a “luxury boutique hotel”. This was my first time in PR, and I was hoping to try a smaller brand hotel instead of going to rio grande for the four season or dorado for the ritz, but I’ve now learned to trust my instinct. If you’re looking for a trashy, near the beach fake luxury hotel, then go ahead and book. If you aren’t, I’d recommend you don’t stay here. For those looking at some of the “better reviews”, I’m unsure if they’re real or if they are likely from less seasoned traveler. Cherry on top: I asked for late check out so I wouldn’t have to wait as long at the airport, and in consideration of my bad experience, they scoffed and said do what you have to, hence where I am now. (That’s my review of the customer service, instead of assuaging a peeved occupant, they challenge me).
