Holiday Inn Express Hotel & Suites Trincity Trinidad Airport by IHG
The room, and facilities were all up to par. The staff were extremely welcoming and provided outstanding service with all my needs. I recommend this hotel to all. Shuttle airport services made travel to and from Piarco a breeze. Thank you all. I will definitely be returning in the near future.

Airport Suites Hotel
Very disappointed with the service and the refunding process. Had to make multiple calls to get a refund and was still charged for the night after being downgraded to a smaller room. The room and hallway had a strong sewer scent upon arrival which was a big health concern for me.
