We chose Martina's place based on the size (big enough for 6 adults), location (near Termini Station), and previous AirBnB reviews (glowing).
We were very happy with the apartment. However, the street it faces is not the fanciest in Rome. There was quite a bit of trash uncollected, which is not unusual in this city.
We were able to easily walk to most every area of the city center, including Vatican City, Trastevere, and Foro Italico. Termini Station is a 5-10 minute walk (Mercato Centrale in the station is a great one-stop shop for food). There are myriad restaurant and shopping options in the Monti neighborhood and along the streets around the apartment. We found more than one rooftop bar to enjoy sunsets without having to go to further reaches of the city.
We all agreed that we would stay here again. Martina and her staff had the space clean and ready for our arrival. All communication with Martina was professional and prompt.
Be aware that the Rome City Tax is due at the end of your stay and is not included in your AirBnb rate.
