This was a very good stay from many perspectives. Specifically the location was relatively close to some of the key Rome tourist sites. We were ~ 1mile (10-15 minute walk) to the Spanish Steps, Trevi Fountain and the Colosseum/Roman Forum/Palantine Hills. A metro stop was also nearby and that proved our choice of transportation to get to Vatican City (~ 2 mi away).
Our host Agnes was also very nice and helpful as she coordinated the car service from airport to the apartment and then at the end of our stay back to the airport. She also met up with us upon our arrival to explain the details of the apartment stay.
Physically the apartment had a modern look and was clean and spacious. We found the on site washer/dryer to be a great benefit as we were able to do our laundry without having to drag our stuff to a laundromat(which we did at our earlier visits in Barcelona/Paris and Venice)
Overall this was an enjoyable stay
