Quiet rooms at Grand Mercure Bali Seminyak
Sound insulation is poor — thin walls permit audible noise from neighboring rooms, doorbells, and external sources. Only one vague positive claim contradicts overwhelming specific negative evidence.
All claims are from June–July 2026, representing recent experiences. No temporal improvement or decline is evident within this narrow timeframe; the problem is consistent across all recent reviews.
What the reviews tell us
Thin walls permit audible transmission of neighbor activity, including conversation, coughing, and sneezing (claims 69118, 71845, 80722, 80863)
Guests report hearing neighboring room doorbells clearly enough to confuse them with their own doors (claim 71853)
External noise from roadside location and adjacent empty block with dogs makes some rooms unusable, especially balconies (claims 67004, 68149, 90569)
Noise severity affects sleep quality, with at least one guest unable to sleep for three nights (claim 68015)
One reviewer reported their room was quiet, though without specific detail (claim 67111)
Sound insulation at Grand Mercure Bali Seminyak is a significant concern. Multiple recent and detailed reviews consistently report thin walls that fail to block noise from adjoining rooms, with guests able to hear neighbors coughing, sneezing, and general activity. The problem extends beyond inter-room isolation: guests report hearing adjoining room doorbells clearly enough to mistake them for their own, and roadside rooms are affected by external noise from traffic and nearby dogs that makes balconies unusable. One guest reported being unable to sleep for three consecutive nights due to noise levels. The hotel's room assignment practices also contribute to the problem—at least one guest was placed in a roadside room despite explicitly requesting a quiet room. Only a single vague positive claim notes a "quiet room," but without specificity or detail, it stands as an outlier against a consistent pattern of sound-blocking failure across all recent reviews.
One Quiet Room vs. Widespread Thin Walls
Claim 67111 (New Zealand reviewer, 2026-07-14) reports a quiet room with no detail. However, nine other claims from the same period—including highly specific descriptions of thin walls, audible neighbor activity, doorbells, and sleep disruption—contradict this. The single positive claim lacks specificity and offers no explanation of room location or circumstances, while the negative claims are detailed and consistent. This likely reflects room-location variation (corner vs. roadside, higher vs. lower floor) rather than a genuine contradiction in insulation quality; the hotel's own acknowledgment in claim 67004 that some rooms are roadside suggests room selection significantly affects experience.
The evidence
Representative quotes from 11 supporting reviewsThey put us in a room on the road side even though we asked for a quiet room
walks fairly thin so can hear alot of nouse from joining rooms
the rooms have door bells and you can hear the adjoining rooms doorbell thinking it was mine
The major issue is that the walls are very thin. I have never experience this in any other hotel around the world. It seems like the walls are made of paper. You can hear the neighbors coughing and sneezing
