Great suite!
I stayed here for three months while doing an internship in Rome. I was alone for the majority of my stay but did have a visitor for roughly 1 month. The space is large, just like in the photos, and there is quite a bit of storage space for clothes and baggage.
The laundry machine is technically shared, but is located right outside the door of the suite so is very easily accessible.
I think the best part of the suite is the location. It is in a very safe neighbourhood right beside the Vatican with many nice restaurants, gelato, and other shops just a short walk away. Also, there are multiple grocery stores really close by. I generally went to Coop for most things and then Pewex for some more specialty items.
I would say the only downside is the windows being on the street side of the building, so on Saturday night it can be a little loud, especially if you have the windows open. However, it is a basement suite so you should expect that ahead of time. Also, the suite is airconditioned so that allows you to keep the windows closed if it's hot which is helpful.
The closest metro station is Ottaviano which is about a 15 min ride to the central station "Termini." If you need to use the metro daily you do get used to it.
All-in-all it was a good experience and was happy with my stay here while in Rome.
