I stayed at One Tijuana Otay for one night. The location is excellent, with plenty of restaurants, bars, grocery stores, and shopping within walking distance. The complimentary breakfast was also a nice bonus.
The room itself was very basic. It was clean, but don't expect many amenities. There is no closet, safe, or refrigerator, and I found the bed to be less comfortable than expected.
The biggest issue was the air conditioning. I turned it on when I checked in around 5 PM, but when I returned later that evening, it was blowing air but not cooling the room. A technician temporarily fixed it, but less than an hour later it stopped working again. By late evening the room was uncomfortably hot. I called the front desk, but no one answered, so I had to go downstairs. I was told the hotel was full and the technician had already left. They promised to update me if another room became available, but no one ever followed up. I ended up spending the night in a hot room.
At checkout I was told that because I booked through Expedia, the hotel couldn't offer any compensation. Parking also costs 100 pesos per night. Great location, but the AC issue and lack of follow-up would make me choose another hotel next time.
