I've stayed in a lot of hostels and the Yellow House is probably the nicest one I've been in. I stayed in a 6 bed mixed dorm and it was very big and spacious. Most hostels try to fit as many beds in as they can, but not here, everyone had plenty of space to themselves. The lockers go underneath the beds which is great for saving space in the room and you can get a lock at reception if you didn't bring your own, which I hadn't. The main door to the hostel gets locked in the night, but if you ring the intercom and show your key they'll leave you in. The bar was really nice to hang out in and meet new people, it had a great atmosphere and drinks were pretty reasonable compared to some other places in Rome.
If I'm in Rome again I'd definitely stay here a second time.
