We had a great stay in Maddalena's apartment. We were stuck in a traffic jam on the highway from Sienna to Rome for 3 hours and she was very nice to get her friend Nicolla to wait up for us when we only manged to reach at 11pm instead of 5pm.
The apartment is great! it is very clean and modern. Very comfortable for the 2 of us to stay in.
Location is also very good. Just a 10 mins walk to the metro and you will be able to go to Spanish Steps in a few stops. It is also just 20 mins walk down the street to reach the Vatican city.
If you are looking for an apartment to stay in, you will not regret with this apartment!
