The people are friendly who host it, but can be loud and smoke by the window in the middle, so the hallway and room air smell smoky when they or other guests do: it filters into the 'nonsmoking' room.
The pipes also grind and moan loudly whenever anyone uses water, the heating system is very loud, and you can hear other guests often in the hallways, or their TVs.
They gave us 6-7 heavy keys to get in so you initially feel safe from the street; but 2-3 keys didn't work (once I couldn't get out of a gate), & the building left open 3 of the doors while they tried to fix it, so only 2 locks actually separate a guest from someone walking in off the street.
We met interesting people there, got lots of exercise walking, it's near the nice park around Borghese Villa, but it would have been nicer if the employees showed more respect to guests. It may just be a cultural or language thing.
If you don't have good hearing or sense of smell and are just there at night, it would be great for the price, with good breakfast, too. Thank you.
