Anna's place is exactly how it is described online. Anna is very thorough with her directions and descriptions so read them and you will be fine. The directions from Rome Termini were very easy to follow but after a few days at Anna's I found that walking to the Termini was much easier (for me). The fresh air was nice and you walk past a park on the way.
One thing to note: due to the time of year 3 metro stops were closed. Trevi Fountain and the Spanish Steps being two of the most important. Ask Anna about other options of getting to these locations if you stay here.
