The cons first:
1. I requested an extra bed, but they said it would be confirmed later. However, until I checked out, no confirmation was given, and as a result, there was no extra bed. Luckily, the bed was big enough for two adults and two children.
2. The hot water in the jacuzzi wasn't too hot, but because Kaliurang's weather is cold, it cools down very quickly.
The pluses:
1. Super clean, comfortable room. Although there is air conditioning, I didn't use it because it was quite cold. The Wi-Fi is fast, reaching the restaurant and onsen area.
2. The onsen area is top-notch: comfortable, clean, and aesthetically pleasing. There's a children's pool, but unfortunately, the water isn't hot.
3. Access to all Kaliurang tourist attractions is close. Across from the hotel is Suraloka Zoo. Merapi jeep tours are also close, but I don't know if the hotel offers jeep tours or not.
4. The food is varied, although the taste is mediocre, but it's enough for breakfast.
