I’m a 21yr old and visited Rome for the first time, wanting a cheap and affordable place to stay that was in walking distance to the city center. Gialel is exactly that. I went during peak season and they didn’t rip me off, and it was a 15 minute walk to Trevi. No AC, but if you simply use the room as a “rest stop”, it works wonders. Clean sheets, bathroom, and friendly staff. Not much more needed than that if you’re visiting Rome on a budget.
