Diletta's cottage was fantastic! My boyfriend and I loved staying there. There was plenty of room for the two of us and it was so beautifully decorated. Most airbnbs are somewhat minimalist/neutral but Diletta has really put her stamp on the place. There are lots of books and trinkets around the place and it really feels like home.
Everything we needed (towels, hairdryer, even some toiletries and food) was supplied. Diletta explained how to use the heating (we visited in December) and was very helpful during our stay when we asked how to work the TV (via message in the airbnb app).
We cooked for ourselves most nights and the kitchen was perfectly adequate for this. Don't expect to cook anything complicated as obviously there is a limit on space but there are so many restaurants and bars nearby you won't have to!
The location is perfect too. Only about 10 minutes walk to the Collosseum, 5 to the Circus Maximus. We walked everywhere during our stay (even the Vatican was only an hour away by foot and we like to walk while on holiday to see more of a city). Plenty of bars to grab a drink or food 5 minutes away. The cottage felt peaceful and was quiet despite being so near to the hustle and bustle.
Our only regret is that we didn't come at the right time of year to make use of the terrace. We hope to return to Rome when the weather is warmer and stay on Diletta's cottage again!
If you are one or two people I would urge you to book it! You won't regret it.
