We stayed at Antonella’s place last weekend and it was about 30€ in a taxi from CIA airport. Eleanora met us when we arrived and was very friendly, she suggested places to visit/dine and gave us her telephone number in case we needed anything.
The apartment is very clean and had all the amenities we needed including soaps, tea/coffee facilities, great air con and a fridge. The only criticism would be that the shower could have been more powerful but it was hot and there were plenty of fresh towels.
Great location - the apartment is about 15 min walk from the colosseum and the metro station is literally 1 min walk away and for €1.50 takes you to all the attractions. There was also a local shop next door and a snack bar.
We would recommend this apartment and we had a lovely stay!
