Ok, this happened some time ago but it keeps bugging me if I was an asshole or not.
I'll start from the beginning.

This guy was a friend of one of my 2 roomates. 

This guy asked my friend if he could've stayed at our home for the summer season. 
We talked before accepting him and eventually he came over.  
 
I went out for holidays in the period going from July to the end of august, with my family. 

P.S.² I sleeped in a room with 2 beds: 1 double and 1 single. Mine was the single, my roomate took the double.

I found my sheets tossed in a basket with some other dirty laundry that didn't belong to me. Then I saw my bed occupied with some other sheets (this guy).

Well, I didn't ask for permissions, it was my house, so I removed those sheets and placed mine. (And, after all in a fairness, no one told me that my bed has been occupied without my permission).

I took this guy sheets, folded them as well and putted aside, in a cool and clean spot. (because, I'm not a barbarian). 

After this, things seem to be fine. 

P.S³ I'm a nurse student. At the time I was in a General Medicine Ward Internship, so I had to wake up at 6 AM, every morning. We had two little drawers, that we used to recharge our phones and other things.

Well, this guy snored like a broken tractor and I have a very light sleep. So, I bought earplugs. 

These earplugs helped me a lot with sleeping but I had a hard time hearing my alarm going off. It would take me some time to hear it and turning it off (on my phone).  

One morning, he decided that my alarm had to be taken out. So he turned it off and I woke up late that morning.

Last straw. I returned home and faced the guy. I asked if he turned off my alarm, and he said yes. I went furious. I don't tolerate people invading my personal space. He replied with "I found my bed without my sheets and clothes out of my drawer". 

Anyways, I replied to him that that was my bed, my drawer and my house and if the princess wanted to sleep in the morning, he could've as well taken his things and changed house. 

He said "how so, I'm a guest, you're acting like this is only your place, shut up" and things along those lines.

My roomate, his friend, didn't say a thing and this made me EVEN more furious. What the fuc*? 

So I kicked him, with the help of the other roommate that was also bothered by this guy behavior (the roommate that helped me had his own room, and he wasn't the guy's friend).

In my country, there is a saying: a guest is like a fish. After 2 days, it stinks. 

TL:DR: "princess guest" was too bothered by my alarm, took possession of my bed without my permission and acted like it was normal, so I kicked him. 

Things worsened between me and the guy's friend roomate so eventually I moved to another house one month after, even if the guy wasn't there anymore.  

So, am I the asshole here?
