This was my first stay in Rome and First time using Airbnb.
I recommend highly this very comfortable apartment situated in a very central location.
I timed 10 minutes walking to Termini Station and 10 Minutes to the Colisseum -12 minutes to Piazza Venezia .
If you arrive early you can wait at the bar below the apartment sitting in the sun with a nice cafe latte!
The apartment was refurbished a little while ago very cleverly and with a very high standard of carpentry .It is a "quirky" apartment :
The sitting room has a single sleeping area and can be private if you close the sliding door between sitting room and kitchen/dining/bathroom/double bedroom area.
There are hidden sliding doors to kitchen and bathroom as well.
There is a very big window/door onto a private courtyard with plants and a clever mirror that doubles the amount of the window and plants.
WIFI worked very well. I could not get the phone signal so got peace and quiet on that front.

The double bedroom area has a very very comfortable bed and no noise at all. THIS HAS TO BE TWO MAJOR PLUS in Rome !!
I enjoyed reading in my bed every evening before going to sleep.
All is very well designed. All the ceilings are wood.
The kitchen is not big but it has everything you need for your holidays - So has the dining area and the bathroom.
There is a big window opening on an inner courtyard with plants and a small one looking on another inner passage. I guess that in hot months the drafts will be very nice.

If you cannot go up stairs then this is not an apartment for you as they are the access to the sleeping areas.

Walking around this area is very nice especially in the little streets around Cavour Metro , 5 minutes walk away .
Termini Metro is 10 minutes.
Walking around you will find all the shops that you need.
On check out if you have a late flight you can leave your luggage at Termini Station deposit area . Look for the post office entrance into the station . There is a lift in the main hall of that area - go down one floor.
Look for DEPOSITO.
It is 6 Euros for 5 hours and 1 euros each extra hour.
The train to Fumicino airport leaves on ground floor Platform 24 which is next to the deposit area in basement . You can buy your ticket at beginning of platform @ 14 euro each way. A train leaves every 30 minutes. It takes 32 minutes to airport.

All in all I am glad I stayed in this apartment and in that area.
I will return and will book my stay in Rome checking first Carolina availability , then booking my flights and not the other way around as most people do.
