We were met at the airport, then again at the apartment, by varying family members- all friendly and efficient! Apartment is lovely, up 4 flights of stairs and only aircon in the main bedroom tho'- but it's clean,lots of space and the terrace is great to relax on early morning and after a long day sight seeing!
It's in a 'daunting' area and you need to keep your purse safe- but got used to it- and it is very handy for the Metro, and there is the best Gelati in Italy only a few mins away on the next street!(Palazzo del Freddo)and one or two nice restaurants.
If you arrive late as we did,it was great that they had left some grapes and water for us but it might be worth asking Adrianno or Yumi to get some coffee/milk/bread for you so you have something for the morning.
Any difficulties were dealt with by the hosts.
They had left lots of great information and maps/transport plans for us to read/use which were really helpful even tho we had guide books.
We booked the Early access Vatican and St Peters tour before we went to Rome- well worth doing- it was the best part of the trip!
Enjoy!
