There have been three recent threads on tripadvisor regarding this Florida-based apartment rental agency.
Those threads included some negative feedback and many posts that were deleted by tripadvisor staff.
I contacted USAParis.com in early May and arranged to rent a one-bedroom apartment in the 6th for four days in early June. The agent I spoke with at USAParis was helpful, courteous and offered a small discount on a newly-listed property he was anxious to fill.
I received their lengthy contract and reviewed it page by page with the agent. I paid a deposit by credit card (American Express, which protects customers against fraud, although other cards probably do, too.).
I understood that the balance would be charged to my card upon my arrival. In addition, USAParis took an authorization for $500 damage deposit, which was never charged to my card.
I arrived at my apartment and found it to be better than it had been described. The key was where it was supposed to be. The apartment was clean and all appliances worked. Wireless internet worked without a hitch. A telephone was available for local calls and for receiving calls.
I had a uniformly positive experience with USAParis and told them so upon my return. I am sorry to hear about others' negative experience and would be glad to provide more details about my rental, if it would be helpful to others. In addition, I'd like to hear from any recent USAParis clients: obviously, if others have had negative experiences, I would be reluctant to recommend them to friends.
Some of USAParis' properties seem to be co-listed with VRBO, but the price is lower on USAParis. Don't know why this should be.
