My brother rented a place with this agebcy last month. After three days the apartment was "robbed". By this I mean a stanger came inwith a key, made a horrible mess, stole the soare key and left. When my brother called the manager he was told NOT to go to the police! He went, anyway.
The agency would not come to see the damage until the next day, but by then my brother had already left (would you sleep or leave your belongings in flat that had just been entered by someone without a key?) and the mess made by the intruders was therefore gone, too.
The agency THEN kept my brother's 500€ security deposit for the stolen key. When I called the owner to complain, he was surprised the manager had not talen my brother to the police station because this has already happened SEVERAL times!!!
I don't know who the dishonest party is: the owner, a manager or a cleaning crew, but it is NOT normal. Fortunately, because of the police report, the credit card company has refused to honor the charge for the security deposit.
Regardless, my brother was very lucky to be surrounded by French family who could help him through all of this, as well as lodge his family to avoid the additional expense of an honest hotel. Ah Paris is HORRID.
