I would recommend Massimo and Simonetta to anyone who's looking for a lovely stay in central Rome!
[About the room] Very nice and comfortable, with one extra bed and a private bathroom just across the corridor which was very small but clean and warm. The only complaint I could think of was the noise coming from the street outside, but given that this is central Rome and I was so tired after my daytime journey exploring the city on my feet, I didn't mind the noise at all. Also three layers of windows also proved that Simonetta did try to minimalize the disturbance of the noise. Besides that, a little breakfast was served every morning at the right time I chose, with a whole selection of different types of tea, coffee and pastries - What a nice way to start a day in Rome!
[About the location] 25-27 mins walk to Colloseum, 9-10 mins walk to nearest metro station, 5-10 mins walk to nearest bus and tram. I particularly felt safe walking in this area - very peaceful among blocks of lovely old buildings.
[About Massimo and Simonetta] Incredibly nice hosts! Although their English wasn't perfect enough to fluently chat with me, I am still grateful for their hospitality and thoughtfulness. Will certainly recommend this place and book again the next time in Rome!
