The apartment is very clean and nice for a couple.
Going to the centre by public transport is very easy and a nice way until midnight. There are many different possibilites to ride (bus, tram, metro).
I would advice to check all the routes on arrival so you know how to get best to the different sights of rome. I also recommend to walk (or run) through the park close beside the apartment! There are three supermarkets and good pizzarias in the area that are accessible on foot.

We had a great time in Rome and are looking forward to come back soon!
For that Lis Mari and her husband are co-responsible! Surely we will stay in their apartment then! :-)
