I only stayed at Matilda's for a couple of days and never met her, but I did speak to her quite a bit on WhatsApp and she was incredibly helpful with check in and travel itinerary. The place was nice and clean, a lot more spacious than I thought it would be, however, there is little sunlight entering the room as the window is situated between two buildings. There wasn't noise from traffic, even though it was really central location, but because it was enclosed between the two buildings people talking, etc could be quite loud. I think it's a good place for a lone traveller as the nearby piazza and streets are always full of people, even when I was leaving at 3-4am so you can feel reasonably safe. I walked everywhere, including a supposed 30min walk to the Colosseum, although I stopped a lot to look at different buildings, etc and I'm pretty sure it took me less to walk there. Roughly 20ish mins I'd say. Either way, there's a bus stop with busses to Termini station and Piazza Venezia 3 mins away so if you'd rather use transport, it's easy. Moreover, there's an incredible amount of choice of places to eat and drink literally outside the apartment and another street 5 mins away. All in all, I'd recommend staying at this Airbnb and Matilda as a host. It's quite cheap for what you get out of it I think.
