Marco was extremely helpful and knows his way around Rome and what's worth seeing. Before we got to Rome he emailed us a list of information and websites we could go to buy tickets for things like the Vatican Museum as well as transportation information.
Unfortunately, due to some unforeseen circumstances on our part were not able to stay the night we had planned. But based on my experiences via email, my contac. with Marco was fast and efficient. I will definitely look him up next time.
