I am a travel agent. So, I have waited a few days to write this review and to keep as professional as possible.
Pros: Location, location, location. Literally steps to the Pantheon and other fantastic sites. Apartment was sparkling clean and well appointed kitchen and supplies.
Cons: Up until check-in Carlos had been extremely helpful. I had rented a 3 bedroom as there were 5 of us traveling. When we arrived we were told that it was 30Euro per person per night more = total approx. $200. We certainly not expecting that. Carlos spoke through his housekeeper that checked us in and would not speak to me live. I only wanted to know where in the policies it stated it would be extra for additional guests. As the housekeeper was texting I was saying to my friends, if it was just 2 of us I could have stayed at the 5star Hotel Minerva. The housekeeper didn't realize I spoke Italian, as she told Carlos that we wanted to stay at the hotel Minerva (error in translation). Carlos told her to tell us that we could go and leave his apartment. He then finally asked to speak to me. Before I could even ask a question, he told me that unless I paid the additional money, I had to leave. If I wanted to stay to just pay the money and be polite. We didn't have much of a choice as at the point there was no alternative. We were left to feel that we had been scammed but did not have a choice but to pay his demands.
While a lovely stay, I would be hesitant to recommend to anyone after being treated so rudely.
