The apartment is near a Metro station which itself is only one stop from Termini. Make sure you take the correct exit from the Metro as it's a bit of a maze underground. Taking the wrong exit (as I did first time) leaves you further away from the apartment.
The apartment itself was very clean and spacious for the 3 of us staying there. The kitchen had everything one might need, expect perhaps a cafetiere capable of brewing more than one cup of coffee at a time. We found a shop literally around the corner which stocked the basics we needed for breakfast. There are supermarkets a little bit further away.
Claudio was an excellent host in every respect. My brother who has a lot of experience in renting apartments in France, disagreed with a couple of the House rules, particularly the one where the guests were requested to deposit their rubbish in bins in a nearby street. As it turned out we had no time to do this anyway, to ensure we checked out on time.
Overall, a great apt. and host.
