I would strongly recommend Simone's place to anyone thinking of staying here.
The place is spotlessly clean and Simone is always on hand to provide any amenities you need and he responded almost instantly when we needed to speak to him.
We felt very safe in the neighbourhood and the atmosphere was exactly what we were looking for.
The location is a stone's throw from Castel Sant'Angelo and St Peter's Square at the Vatican but is a good half an hour's walk from some of the city's other attractions. This is not a negative fact about the place but some homework on the transport system would certainly help!
