Riccardos appartement is a really great place if you want to stay in Rome. You just have to walk some minutes to the metro station although from there it's some stations to go to "termini".
The flat in itself is just a super cool place. everything you need in the kitchen, a very great terrace to hang out for example for breakfast, big bedroom, good bathroom with a very nice shower. Also a supermarket is just next to the house and you have various options for some untouristy pizza or pasta in the neighbourhood! highly recommended!
