The apartment is about an 8min walk from termini, and that was with a case and pushchair. Giuseppe was there on our arrival and showed us around the apartment. He also showed us on a map recommendations for places to eat and how best to get to the tourist attractions. On the second day we had a question about some equipment left for our baby, he answered within 5mins and it was sorted within 30.
The flat is on the 4th floor but lift is fine. You can hear noise from the restaurants down below at night but was never enough to stop any of us sleeping. Shower is snug so might be a bit of a challenge for anyone 6foot plus.
We enjoyed the restaurants too much to cook at the flat but all pots/pans/crockery is there if you choose to.
Location really handy for the metro, we ate at the closest restaurant La Famiglia on one of the nights which was great. We walked everywhere, 20mins to Trevi Fountain, 25 to colosseum and 1hour to the Vatican.
Would recommend and also stay there again.
