Noisy room - unable to sleep.
Just returned from a two night stay in Palma which unfortunately felt a little longer due to a severe lack of sleep. We stayed in a Petit Double (Room 624) which is small but had everything we needed for a short break.
However, the constant noise in the room, which I assume as above a plant room at the hotel is unacceptable. There is some kind of machine that makes a constant loud buzzing & vibrating noise all day and night. When we complained just after 5am after getting no sleep at all, we were told it was the connected restaurant and nothing they can do. We weren't offered a change of room as I believe the hotel was fully booked. We spent the next few hours with earplugs or earphones in listening to a "sleep" playlist to try and drown out the noise. It never worked!
The following morning hotel staff said it wasn't the restaurant, but a machine they are obviously aware of and nothing they can do.
How can you sell a room that you know people will have difficulty sleeping in? The room is tiny so the only value it could provide is a place to sleep comfortably. Our room was also next to a cleaning/laundry supplies cupboard so expect banging and clattering in the early hours from the cleaners along with their mobile phone notifications pinging every few minutes.
I would imagine other rooms/floors in the hotel could be great just not the one we were given and I would not chance staying there again.
