This apartment is extremely dark and damp and smells like mold.
The host was responsive and thankfully offered to refund us after we decided to leave because of the moisture & mold smell and lack of WiFi. Great location if you want to be in the center of Palma, and a good size for a couple.
Upon arrival, we immediately noticed that the apartment felt like a cave in that it was very damp and dark, and the windows did not open (and faced interior walls, so no light could enter anyway). There are multiple doors and you can hear people on the street as if they were in the room with you. The apartment is on the ground floor of a very rundown building, and does not feel very safe. There is no way to change the air conditioner setting (it is set to 25 degrees Celsius / 77 degrees Fahrenheit), and in the middle of the night, water started pouring out of the air conditioner (this lasted all night). Also, the WiFi abruptly stopped working.
Maybe the dampness is seasonal? If the lack of fresh air & natural light and the presence of moisture and mold smell would not bother you, this would be a good place to stay.
