We really enjoyed our stay in Rome!
We arrived at 10 am at the appartment where we could store our luggage till everything was tidied up. We only met Helene who was very kind.
The listing description is accurate. But they do not mention that the appartment is in the first floor. They also provide a folder with useful informations which I liked a lot.
But you have to be aware that it takes some time to walk inside the city (to Pantheon about 45 minutes). Of course you can use the bus or metro.
Conclusion: the value for money is very good!
