The first night I was bitten by bed bugs all over my body, so the next day I show it to the people in the reception and I asked to change bed, hoping that it wouldn't happen again. Sadly the second night it happened again and at that point I've decided to leave the hostel. I was supposed to stay there two weeks and I ended up staying two nights. I had to move to another place, wash all my stuff, put my backpack in a plastic bag and spray it with a insecticide. It has been very unpleasant, but after I left the hostel I didn't have any more bed bug problems. Before arriving in this hostel I was at my mom's house and my backpack was bright new, I never got this kind of problem before.
The other unpleasant thing is that the cleaning lady, after she has been told about the problem, started to treat me in a very bad way and I felt extremely uncomfortable and mistreated.
The good thing is that the guys at the reception were very helpful and understanding and after talking to the owner they gave me a refund of the nights I had left, which I really appreciate. I also wrote a email to the owner myself, to explain what happened and they were very sorry for all the inconveniences.
