We have stayed in Yolanda's place for 5 days when in Rome.
Flat is very comfortable for 4 people, clean and very close to Colosseum (10mins walk) and any other sights (Trevi Fountain, Piazza Navona 20 mins walk) etc. Yolanda gave us all info on nearby restaurants, shops etc. Great pizzeria and gelato's down the street. Even though apartment is near small piazza (down the street) it is located in quiet area and you can sleep comfortably at night after you had nice night stroll down busy streets enjoying Italian atmosphere and some wine. There is no air/con but in every room you have big fans which were enough for us to sleep in July. Perfect place if you want to live like romans and do sightseeing without long commutes.
