Location location location. Fast/inexpensive internet. Accommodating host. Safe neighbourhood. Everything close (market, grocery store, farmacia, bank, metro/bus etc.). Natalia went beyond in all facets of the stay: providing advice, language translations, shopping and commerce tips, directions; she found a balance so I had as much space as I wanted yet helped me achieve the things I hoped for (eg. living "normally" and not as a tourist). She ensured she was always available and responsive. The Prati neighbourhood was perfect for me; just far enough away from the energy/sound of central Rome, but close enough to walk anywhere within 1/2 hour. My activities focussed around the centre, to Borghese gardens, to Villa Pamphili, to Vatican, to Olimpico Stadio for futbol matches. During my month stay, I never found myself wishing I had stayed somewhere else. Thank you, Natalia!
