The Aventine hill is one of the best spots to stay in Rome – and this little house/apartment is perfectly situated. You can reach pretty much everything on foot, and the local restaurants etc. are great.
As some others have noted, it can get quite hot in Rome, but if you don't mind the windows open (and the resulting mosquitoes), then the basic fans Diletta provides do a fine job of cooling things down.
The place is showing a fair bit of wear and tear (the photos are clearly pretty old), and we had some maintenance issues during our stay, but overall enjoyed our stay and found it a good alternative to pricier hotels. Diletta and her associates were very attentive hosts and communication was excellent.
