Mario's wife is helpful. Helped us with the luggage up the few steps to the lift when we checked in and also when we checked out. She was responsive. Gave us a map and orientated us.
Allowed us to check in early and leave our luggage there till afternoon on check-out day.
The apartment is clean and daily cleaning is carried out.

It is about 10-12 minutes walk from Roma Termini and a short walk to the Vittoria Emmanuel metro.
