Antonella and Marcus is very personable and flexible pair (they patiently waited for our delayed arrival). Their apartment (beautiful, clean, very soulful, full of beautiful paintings) is in the city center, 200m from St.Petr's basilica. Near the house is a metro and a bus stop. In Via Ottaviano is a lot of good pizzerias and bars, it's a great place to shop. The best location for visiting Rome, we really enjoyed it. We will return soon. Thank you Antonella!
