Nightmare scenario for us
Upon arriving the room had a musty smell like it had not had fresh air for some time.
After the first night my husband developed bad asthma and flu symptoms. the following 2 mornings he was worse, we put it down to the room as we were out all day everyday he would clear up during the day and then wake up feeling awful.
After 3rd night we decided to carefully look at the room which I wish we did first.
I noticed black mould on the curtain which prompted us to remove the sheets from the bed and the entire mattress was covered in black mould. We immediately packed our stuff and called the host who came over and looked and apologized saying he did not know because they only change the sheets and not the mattress protector (but it was clear to see the mattress protector had been cleaned as it was not dirty).
We then had to spend our holiday money on the only last minute accommodation we could find and cut our holiday short. NOT RECOMMENDED!
