Poor air quality in the room (no windows), no ventilation and it felt like the room hadn't even been aired out since the last person stayed there. I have stayed at the hostel several before, and it was not an issue, but this time it was unbearable in the room. The staff came to check, and even though there was no airflow, they were pretending like it wasn't a problem. There were several other guests that complained about the same things that day, but nothing was fixed.
