Very good location. Giuseppe is very helpful and gives you a lot of info and detailed steps on how to reach the apartment. He was waiting for us outside at 23:00. He also replies very fast to any message.
The apartment is close to the Colosseum (11 minute by foot). Good bed, slept like a baby, even though there is some noise due to traffic outside. Very clean. If you don't want to cook (like fry onions), then it's a great place to stay.
Oh, and you will only get a room inside an apartment where there are other rooms for other guests. You may need to take this into account until the pandemic is over. We only saw the other guests twice during our 7-night stay.
And if you're staying for longer, make sure to bring clothes, because there is no washing machine.
