I can't say enough good things about this place! After booking, before coming, I had a few questions that were answered promptly. The location is perfect for walking to anywhere in ancient Rome, and to the Metro. We were greeted at the door the night we arrived, helped with our luggage, and shown around the flat, noting basic things we needed to know about the space. The flat was SUPER clean, and had all the basics we could need. (We did not cook and we don't drink coffee, but I did see that there were coffee pods {for a coffee machine, I assume, but didn't look}, tea bags, and basic cooking needs: oil, spices, pots, pans, and dishes.) Cleaning supplies and trash bags, along with the detailed instructions for separation of trash that Rome requires, were all there.
Things of note for other travelers:
The stairs. Oh, the stairs. I don't count this as a "negative" because we were well aware before we got there, but they are long and steep. When we go to Rome, though, we go down once in the morning, and back up at the very end of the day, so it really wasn't THAT big of a deal for us. If you're an in and out kind of person, these stairs are a killer.
Both beds have very firm mattresses. Again, not a "negative" because that's a personal preference, but just something to be aware of.
I would recommend this flat to anyone. Even with the stairs, the value of the location is excellent. We couldn't have been happier!
