We had a very pleasant stay at Mercure Ancol. We booked a Deluxe Ocean View room, so we could see the ocean, the gondola, and Dufan from our balcony. The room was very spacious and clean. Although the bed was a single, it was quite large. There were plenty of power outlets. The only downsides were that the sofa bed made a noise when we slept on it, the TV wasn't a smart TV, the refrigerator wasn't cold, and the Wi-Fi didn't reach our room. Breakfast was quite tasty and had a good variety. Plus, there was a coffee station with staff on standby to prepare drinks. There was a children's pool with a water slide, as well as an adult pool. The playground was quite spacious and air-conditioned. There was a ball pit, two billiard tables, table tennis, arcade games, and VR games. Staff were also on standby to help the children play in the playground. Based on the above experience, we have no hesitation in recommending this hotel, and hopefully we'll have the opportunity to stay there again.
