Great little place to stay in for a quick city break, a few hundred meters from the Colosseum.
The location is excellent - lots of restaurants very close and cafes for breakfast, plus only 2 min walk to a tram line, 5 min walk to the Colosseum + metro line.
Getting into the hotel was a little tricky at first - this is really a large flat converted into a series of rooms on the first floor of an apartment block, so you need to get into the block first - so make sure you call the owner when you arrive, she is very friendly and helpful and has good English.
The rooms are small but adequate for a quick city stopover. The bed is comfy, the shower is hot and there is a kettle and some tea bags.
It does get quite noisy at night due to deliveries, road sweeping, garbage collection, but I imagine this is true anywhere in the city.
