This efficiency is in a convenient if very unlovely neighborhood.
It felt rather like a college dorm room, but was perfectly serviceable. Better for long stays, thought be careful to clean the kitchette well as not doing so costs you a €50 cleaning fee. But the front desk staff were excellent, nice to have space, the fridge and dishes and such. Did not cook more than hot water, and not having a kettle that meant using the stove top and a pot.
The location is convenient to shops and the metro and with some research, some great local restaurants. The neighborhood is a little down rev, but not specifically unsafe just feels a bit off, and for Italy, pretty grim. . The grounds do include a pool (smaller than it looks on the website but clean) and a lovely garden on the property. We spent each later afternoon there with our own bottle of wind and snacks, a great rest from the city noise.
