We stayed at Leonilde's for ten days this April-May. She was great and very welcoming! She prepare a large breakfast tray for us and left two single trip metro tickets for us to use. Moreover, our flight back home was scheduled for very late in the evening and she offered us to leave our suitcases at her apartment for as long as we needed without any additional charge - it was a life saver!
Leonilde's apartment is very lovely, quiet and has all the conveniences. It was crystal clean when we arrived and even had all the bathroom necessities. The balcony is nice too - you can even have breakfast or dinner there, if it is warm enough outside. The location is great - 5 minutes walk to the orange metro line and only four stations away from the city center. Besides, it is 10 minutes walk to the train station, which makes commuting to-and-from the airport really easy (the train costs 8 euros). There are many small stores and inexpensive places to grab a bite in the area (consider New PizzItaly), but we preferred walking to Re di Roma (10 min walk) to buy groceries at the Punto Simply supermarket and have amazing and very inexpensive coffee with sweets at La Cannoleria Siciliana - the best coffee shop and bakery ever! We were completely satisfied with our stay. If we come to Rome again, we will definitely stay at Nilde's!
