Location - the best of the best! :) About 10m walk from Trevi fountain, 2km from Coliseum. You can find very good restaurants and small shops just 3min walking from apartments. Of course, there are not parking places next to apartment, but you should avoid car rent in Roma.
Apartment has 3 bedrooms. 2 of them is connected with bathroom, so its shared to 2 bedrooms. 1 bedroom is in the corner of house, very near Piazza Navona - so it can be little bit noisy at night.
