If you do not mind a "Noise Sensor" is placed in any Deco Apartments, you can rent their apartments.
We were not told, nor the contract has stated there is any sound measurement device planted in the apartment when we moved in. We found out later on that there is such device. This is intruding the tenant's privacy. They have an app to show live data and someone will know when you are in the apartment or out of it.
I would not rent this apartment if we knew there is monitoring device.
