Massimo's apartment is very well located within walking distance of the lively Trastevere district, and yet in a quiet area itself. It's equipped with all basic things and there's an AC, which was a huge relief to us in the blazing heat of August. The only inconvenience we had was needing to clean some water that was dripping from it, but we weren't too bothered by this. Be aware that all electric sockets in this apartment are the Italian type - we did find one adapter in the apartment and had brought one of own too, so we could keep all of devices charged.
We also had a rental car that we parked on the street. It was affordable (4€/8h and nighttime was partially free) and we could easily find a parking space in front of or very near the house every time.
Massimo is a very kind host and we had a great time staying at his lovely apartment.
