The guest house is very close to the Roma Termini station, you can walk to the guest house in a minute and it has a lift (elevator).
The guest house is very nice and clean, it includes a delicious breakfast! The hosts are very nice!
When we could not make it to the breakfast time, they gave us a coupon for a nearby restaurant for breakfast which we used and was very convenient because we were leaving early to the airport from the Roma Termini.
