I have to star saying that this was our favorite apartment from the whole trip.
Locate in the old Jewish Getto on a building from the 15th century, a block from the Tiver river and walking distance from the Isola Tiverina and Trastevere (by far the best area to eat the area).
The apartment is a 2 levels small apartment with a very wam felling, decorated as an eclectic artist studio, has everything you need to enjoy your visit to Roma, a beautiful full bedroom on the meesanine overseeing the living area, with a very high curved ceiling that is accentuated by an amazing glass fixture (I will call it piece of art), the bedroom has hardwood floors and the rest of the apartment travertine floors, is very quiet, we really feel like at home at this loft.
Maurizio and Fabio had fruit juice and water in the fridge for us, also two big bowls of fresh delicious cherries on the table, as well as a bunch of biscotti and cornetos; coffee options where from the lazy instant coffee to a very Italian espresso maker and a a pod coffee maker.
As soon as we arrive we got a map with all the interesting "touristy" attraction that Roma offers, as well as few restaurant recommendations in the Jewish Getto, and have to say, we kept going to the area and trying a variety of italian and Jewish menus.
Everything is walking distance from the apartment, we always felt very safe walking even at night after a nice dinner in Trastevere which is as we call it "our area" for restaurants and trattorias.
There is a tram station less than a block away that takes you all the way to Piazza Nenezia and you can definitely walk from there to the coliseum.
I was happy to run in Roma, first a total of 4 miles on a very safe sidewalk all around the river. Second time was an amazing experience running by the river then turning to run inside the Circus Maximus and taking the streets to the Coliseum and back, for a total of 4.25 miles.
This area is very safe and friendly, with a lot of things to do and see.
