When people say it's a 5 min walk from Termini they are right. Leave Termini through main entrance, walk 3 - 4 blocks to via Varese, turn left and in maybe 100 meters you are at #5, on the left. If you're going to run around all over the metropolitan area like we did, quick access to Termini is invaluable. The entry gate(s) to #5 bang loudly when opened & shut. Traffic is loud, and people outside tend to yell. We heard this is common all over Rome, so take earplugs if you're a light sleeper. Don't worry about security. There are 2 heavy metal entry gates to the building, a locked entry door to the AbNb rooms, and locking doors on each room. A.C. in the rooms worked well. The only fridge is a small one in the common area and it's not really adequate. Too small and no icemaker. This wasn't a big deal however. Overall, very fun stay.
