DolceVita is right! It is definitely a sweet life being so close to the Colosseum and accessible to the rest that Rome has to offer. Giordano is an amazing host who puts a lot of thought into his guest's comfort. He's included an impressive collection of Twinnings teas, espressos, instant coffees, but also things like pantry staples (oil, salt, some seasonings), and places to put things like cups and a storage tower in the washroom. He was super responsive and made getting there and checked in a breeze. The flat itself is super comfortable with tall windows that open for a lovely breeze or close for total silence when the noise from the road gets annoying. The light in the flat is lovely and the kitchen is very modern with clean lines. we quite enjoyed sitting around with some wine and nibbles discussing the days adventures. He uses good linens and a great supportive mattress that my back appreciated. In speaking with Giordano as we checked out I wish I could rate even higher- just a really lovely human being. He is well traveled himself so he understands what you need when you're away from home.
Also, pay attention to Giordano's recommendations in his guide...Trattoria Morgana was my favorite by far, but in this area of Monti there is no shortage of fabulous places to eat.
