So, I found the location amazing, near the Vatican, the closest Metro Station and the main touristic sites.
The only problem I had was on my check-in, there was a mistake made by the host and as a result, I was found waiting outside for an hour for another traveller to come give me my key. The only alternative that was given to me then, late evening, was to sleep in the mixed room, option I refused. I asked for a discount or other compensation, it was refused. Luckily, through all of this, I was given the wi-fi code before arrival, so I was able to get connected to the host and communicate the problem. I stayed for 4 nights, shared the room with about 5 girls and none of them had this problem, so I guess it was an isolated situation.
All in all, I enjoyed the stay. The room is cleaned up everyday. There is just this bathroom door which is a heavy metal door and is pretty noisy. Also, there was a blanket in the closet the first night but it was removed on my last night and I got pretty cold.
But the rest was pretty good, considering other hostels I stayed at.
