Nice vibe hostel, great kitchen area downstairs with all facilities. We made great use of the kettle and shared fridge and did some book swaps.
Booked a double room and had bites on my legs, not sure what from. We left at 7am to go to Vatican city and I left a note at reception asking for my bedsheets to please be changed, but this was ignored for some reason, which was pretty disappointing. Another night spent scratching which perhaps could have been avoided.
Over 4 nights the beds weren't made, bins not emptied and towels not changed.
On this reason alone I can't vouch for the comfort of the rooms and the linen, or the attentiveness of the staff.
But it has to be said it is a nice comfortable place with a pleasant vibe and easy commute to Termini station.
