We just completed a four night stay here.
The apartment is very comfortable. It has a modern and fun decor and includes everything you could need. Take a look at the photos... this is what sold it for us and it did not disappoint. There are two double bedrooms and two bathrooms which was great as we were two adult couples staying. we also loved the Kitchen and raised dining area... very cool.
The location is amazing. A minute walk to the Colosseum and two minutes to the Roman Forum... everything else in Rome was easily accessible. We walked everywhere and didn't need transport once - though you might need to if going further than the main sights.
Andrea arranged our transfer from the airport and his friend was there to greet us as we got out of the car... which was great. Looking on a map I was concerned we'd get lost! Alas the Apartment is very easy to locate. If we visit again we would definitely stay here!
If you're thinking of staying here... do it!
Have Fun!
