Nice place, very close to Manzoni metro station and a 20 minutes walk from the Colosseum :)
Easy to access from Termini too :)
If you arrive to the train station I really recommend to take the 2 stops with the metro from there.
The bed is huge, very comfortable and the common kitchen is well equipped.
The whole place is very clean.
Room #5 facing the road and the door is opening from the common kitchen, therefore it is sometimes moderately noisy (during breakfast and when the traffic is bigger). However after midnight it is calm and you can have a good sleep.
We could leave our luggage in the common area after we checked out, so we could enjoy our last day very well :)
Also the staff is very nice and helpful :)
I really can recommend this accommodation :)
