My stay at Yael's place was great in every way.
The room and living conditions are very comfortable. The flat is a several minute walk away from a metro station and it takes 20 minutes to arrive to the center.
Yael is very hospitable, thoughtful and ready to help. If not her I would have missed my chance to see Ostia Antica or not have tried real italian homemade yammy pasta :)
I definitely recommend staying here.
