We loved Arianna's place. Close to the Piramide stop, and easy to get to Rome Termini. It's also easily accessible from Fiumicino which was great. The place was beautiful and welcoming.
Just some heads ups:
There is a washer (as listed) but their isn't detergent for it.
If I'm not mistaken, we were greeted by someone besides the host but he was very kind and very helpful so we didn't mind at all.
Our one con was that it took a little bit of time for the gentleman who let us in to meet us despite us letting the host know ahead of time when we would be arriving. We waited outside for probably 15 minutes, so nothing too horrible but it is worth noting.
Thank you so much for the great stay!
