I would rate my overall experience as satisfactory.

Pros:
Though the host was away on business she arranged for her colleagues to
facilitate the check-in and check-out process.
- Hostess extremely responsive and helpful before and during the stay.
- Always responded incredibly within minutes and answered any questions.
- She even helped us find tickets for a fast train at a good price from
Firenze.
- Safe and secure location and building.
- Very clean and tidy and looks as pictured.
- Bright and spacious room with a good window facing the street.
- Fast and reliable wifi.
- Private and clean bathroom, though not en suite.
- Fully furnished and has convenient amenities such as an iron, fully
stocked kitchen, hair dryer etc.
- Washing machine and a clotheshorse, if you would like to do laundry for
free. We bought detergent at a nearby store.
- The proper kitchen is fantastic and you can make breakfast or any meal
and get groceries from the nearby stores.
- Delicious gelateria right below the apartment; be sure to try their
flagship flavor.
- Good pizzerias and grocery stores within 50 metres and a large food
market nearby.
- Not a touristy neighborhood at all so you can experience a rather more
authentic Rome.
- Helped us book on very short notice.
- Magnificent Borghese gardens are easily walkable and just 10 minutes away.
- Extremely close to the Museum of Contemporary Art.
- The Spanish Steps and the Treviso Fountain are just a brisk 30 minutes
away.
- The apartment is a short bus ride from the Rome Termini station and there
are many buses from there. This is convenient if you are taking a train to
Rome.
- There is a bus stop 3 minutes away from the apartment with several buses
leaving from there. (However, remember that buses in Rome are not on time
and unreliable so plan with a buffer.)

Cons:
- If you are in a hurry or don't enjoy exploring on foot, then note that
the Colosseum is 45 minutes away and the Forum is 50 minutes away by walk.
You can take the Roman buses or a taxi, but there can be a lot of traffic
as in most congested cities.
- All the power outlets in the private room are of the Italian variety. So
if you have the standard European travel adapter that comes with most kits,
you can use the outlet in the kitchen where this standard adapter works.
- On the first day, we did not have the option to leave our bags, if we
arrived before 2:30 PM, so we could explore without our bags. (This did not
inconvenience us because we just planned to take a later train. If the host
were in town, it may have been different.)
- The check-out time was 10:00AM as written in the description, which
is apparently a standard check-out time in Italy, so just plan accordingly.
