My wife and I stayed for three months in Isabella's lovely apartment. The apartment is clean, bright, and beautifully decorated. The view of Santa Maria Maggiore from the living room windows is magnificent, especially at night when the church's dome and bell tower are lit.
The apartment's location in the Monti neighborhood is incredibly convenient. If you like walking, as we do, you can literally walk to anywhere in Rome. If you prefer public transport, there are numerous bus and subway stops nearby. Roma Termini, the main train station in Rome, serving all of Italy and other European countries as well, is reachable in 7-8 minutes on foot. There are several supermarkets within a couple of minutes walking distance.
The apartment is spacious and the sofa bed in the TV room, used by our children when they came to visit, is very comfortable. The kitchen, where we made dinner five times a week, is well-equipped, and the bathroom is comfortable as well. The air conditioning, essential in the summer, cools well. The Wi-Fi is strong and reliable.
Last but far from least, Isabella and her husband are extremely attentive landlords. In the first couple of days we requested a microwave, since we were going to be cooking so much at home. Isabella brought it within a couple of days. After about a month the Wi-Fi I crashed and they fixed it immediately. Most important, they are friendly, considerate, and generous.
We strongly recommend Isabella's apartment in the center of the Rome.
