I stayed in Paola's apartment with my partner for a week at the beginning of April.
Paola was incredibly helpful and friendly throughout, from check in to check out! She was happy to give us tips about what to do during our trip, and gave us advice whenever we needed it. The kitchen was well stocked up with breakfast food, as well as a freshly baked cake which was a pleasant bonus! The apartment is relatively compact, but very comfortable.
There is a bus stop right outside but we didn't use this as the metro is so easy and inexpensive. A ticket costs 1.50 and will get you to all the main attractions within 20 minutes. The station is only a 5 minute walk away.
The apartment is in a residential area and there are plenty of shops and restaurants within easy walking distance. There's also a gelataria right opposite which is ideal!
I would definitely recommend this apartment as it is great value for money!
