We spent three days and have only spoken with the agency through messages and the truth is that their service has been a disappointment from day one.
In the first place they gave us only one hand towel for the 4 of us, when I asked for more they told me that the cleaning lady was going to take them the next day but nobody came and no towels were left outside the apartment.
In the bathroom there was a curtain missing and the neighbors could see us showering, they didn't come to fix it either.
The cabinets were dusty and last but not least we were waken by a noise during the night and we found a rat in the bedroom.
Again the agency said they were going to check it out but didn't even bother to say they were sorry for all the inconveniences.
Other than that the apartment is in a very central area but away from the typical noise of Paris, so perfect at night.
It is a second floor without elevator. The flat is fairly well furnished but lacks kitchen basics, things someone would expect to find such as oil, dish detergent, a clean sponge etc, and it is quite small for 4 people.
