Hi! I'm new to hosting and recently got this one guest complained about the same thing.
Here's the thing, I'm in Malaysia, and my listings are in Kuala Lumpur, the capitol of Malaysia. Apart from the praying sound, since it is even near to a hospital and some embassies or government buildings, there are constant sirens from ambulance and police vehicles escorting VIPs. I knew clearly that this place will never be peaceful and quiet, hence I didn't even try to describe it as one.
But this one guest complained about the prayer sound, not others. He claimed that he didn't hear any of this in his previous stay in another listing (just a street away from the current one he's staying). I find it rather funny as you can't really miss the sound if you're staying in a Muslim majority country, especially in a city with dense population.
Currently, I just advised him to close the curtains (full block sunlight) to reduce the sound. He haven't read the message, so I would like to know if there's any better solutions than refund, just a backup plan if he did ask for another solution.
Thank you in advance.
