The room itself was fine, the owner of the hostel is kind and helpful. The only thing that bothered us is that the neighbor watches tv really loud early in the morning so we didn‘t sleep very well because of the noise. Because it is an hostel, we shared the kitchen with other people, and someone started to clean plates at 5 am which also disturbed our sleep. The apartment is located near the center (colloseum, piazza venetia, etc.)
Overall a cool experience.
