When we arrived at the room, it turned out we got a room with a less cold AC, finally the AC technician came, and after checking and dismantling the top, the room was finally cold again. Thank you for the service.
As for the swimming pool, the kids didn't get to swim, because the pool is only one size for adults, so the swimsuits weren't used.
Coincidentally, we stayed on Saturday and checked out on Sunday, because in front of the hotel there is a CFD along Jalan Slamet Riyadi.
