The apartment has all you need and even more. You will find basic kitchen utilities (including things like coffee, salt and sugar) and bathroom (towels, shampoo, toilet paper). There are a lot of maps, guides and leaflets you can borrow to get around Rome. In the evening, you can even chill by Netflix ;)
The location is good, railway station 5 minutes walking, some buses/trams nearby , 20 minutes walk to lovely Trastevere district with great restaurants. Shops and cafes nearby.
Monica is really helpful host, easy to reach if you need anything. You can drop the key in the mailbox if you leave early.
You need to keep in mind that this is a basement apartment so the daylight is rather weak and it is not very spacious. It also can get quite noisy when you open the window, but air conditioning works fine.
In overall, it's great value for money and I recommend staying in Monica's studio!
