we are very sorry that you have had these inconveniences.
As for the humidity in the bedroom, which came from the bathroom, you could open the bathroom ceiling window that we normally keep closed to prevent our guests feel cold during the shower, also in the closet there is a very efficient last generation dehumidifier, we use it in the winter throughout the house, to prevent humidity.
Honestly, during spring, summer and autumn, no one has ever reported this problem, so we do not use the dehumidifier, but if you had sent us a message about the problem, we could have helped you.
The bed was replaced 2 months ago while the mattress is one year old. I thought it was all comfortable but I will check the condition of the bed as soon as possible to make sure it is not damaged.
As for the noise, you can hear the street noise, although it is mostly pedestrian; on Saturday and Sunday it can happen that there is more movement and noise than usual.
