This was my first time to Huatulco and it was great! The staff was super knowledgeable about getting us a rental car, surfboards, local dining and drinks. The beds were really comfortable. They were so comfortable, my friends had to wake me up to get us going out the door. We shared a beautiful two bedroom suite on the third floor with an amazing balcony and chill pool. The main pool was great too. It's a swim-up bar type of pool rather than a diving pool which really lends itself to the beach vibe of the town.
It was also a great central location to visit different beaches and towns within an hour or two.
TLDR: Price was right for lodging and food in the area, great staff, great room, great location.

I just got back from 8 nights at Hotel Plaza Huatulco and loved every minute of the trip. The hotel employees were friendly, attentive, and always happy to help answer questions or offer suggestions. The room was clean, comfortable, and spacious and offered great WiFi and cold AC. The onsite pool (with swim up pool bar) was the perfect place to lounge after a morning surf, and plenty of palm trees offered shade and a great place for a hammock. There was a restaurant and convenience store onsite, and plenty of other shopping restaurants, beach stores, souvenirs, coffee shop) within walking distance. Surfing was the main reason for my visit and this location was great, with ample breaks within an hour and a half both north and south. While many people come to Oaxaca for Puerto Escondido's famous wave, I enjoyed the waves down south a lot more with plenty of unnamed dirt roads giving way to empty point breaks. There's a wave less than 10 minute away that worked every day, with a couple of casual seaside restaurants serving cold beer and fresh fish. There is easy beach access just a short walk from the hotel, or if you have a car all of Huatulco's beautiful bays and beaches are just a 5-20 minute drive.
