Our room on the 4th floor got broken into on the 4th night around 3:30 AM. My partner woke up and prevented the thief from stealing our stuff (laptops and such because we came there to work). It's yet unclear how the thief got into our room, but he must have had a keycard or anything. The employee working that night's shift called the police for us and got us another room, but we felt very unsafe the remaining two nights. We took our stuff with us everywhere we went and blocked the door with chairs when we went to sleep.
Also, the complex is in the midst of a party area. There are multiple clubs immediately next to the hotel. With a sea view room the music can be heard from noon to 04:00/05:00 AM. We hadn't done enough research to know this upfront, but unless you want to party yourself, don't book a room here. When we asked for another room, we were told the hotel was fully booked (which seems unlikely to me given the time of year). The rooms are very poorly isolated and the balcony door, for example, could not be closed at all. There's a lot of stuff broken in the room or poorly maintained. The floor of the room was also very dusty, probably from the sand that could blow in through the balcony door which could never be completely closed.
When the sun doesn't shine, the rooms are very cold as well and you're not able to turn on the AC (cold or warm) unless it's between 7:00 PM and 2:00 AM, which means we were freezing during the day. The hotel has signs which say this is due to an energy emergency, but I think they should just find another solution for their guests.
All in all, Mallorca is a beautiful island, but I definitely would NOT recommend this place.
