The apartment is very conveniently located midway between Centre Pompidou and Forum des Halles, and the top floor setting is very bright with nice views over rooftops and of the street scene below. It's also a spacious apartment with a large living room, a functional kitchen, 2 good sized bedrooms, and a bathroom with a tub/shower combination. Unfortunately there are aspects that would cause us not to stay here again.
The main issue is noise from the street, which made it difficult to sleep in the bedroom facing the street. Even 6 floors up with the windows closed, there is a lot of traffic noise from the adjacent Blvd Sebastopol, including a large number of sirens. We were surprised that even with the windows closed we could distinctly make out the content of shouting from the street below, which often continued sporadically into the early morning hours.
The numerous southwest facing windows make the apartment very bright and offer very nice views, but with no shades, also quite a bit of heat. Even though there was only one day on which the temperature rose above 73F during our stay, we needed to open windows nearly every day to be comfortable. Without air conditioning, the apartment is likely to be very hot during a heat wave.
The issues above are more general features of the apartment, but there were also some things under the owner's control that reflected badly compared with other properties where we have stayed. First, the mattress in the bedroom by the street definitely needs to replaced. The mattress appeared to have been compressed so that the coil springs are right at the surface, so the effect was lying on a thinly covered wire grid. Midway through our stay we decided to turn the mattress over and found that it is a "no flip" mattress that apparently had already been turned over because a spring right in the middle had totally popped out creating a sort of covered pogo stick to navigate around.
Second, the owner has maintained the bedroom closets as private space, so there is no place to hang clothes in either bedroom. There is a closet across from the kitchen equipped with a total of 4 hangers. Third, it may be a positive feature for female travelers that the toilet seat does not stay up, but for 2 male travelers, it was a real annoyance. Fourth, the ultraflat lowback sofa in the living room shown in the photos is every bit as uncomfortable as it looks.
Finally, when we returned from dinner on our first night here, the coded entry for the door to the lobby did not work, and we noticed an alarm going off at the door. Fortunately, the woman who checked us in let us know about the alternate entry around the corner through the rubbish disposal area, and we were able to use that. We mentioned this is in an email to Patrick the next day, and he responded "I know, the neighbor is calling someone who will come fix it." When we left 12 days later, the alarm was still going off. Fortunately we couldn't hear the alarm in the apartment on Floor 5 (it must have been maddening to residents of the lower floors), but the situation raises questions about the management of the building well beyond the control of Patrick who rents out this unit. Periodically during our stay we found that someone had managed to bypass the entire coded entry system so that the door to the building simply pushed open, thus making it totally insecure.
I don't like to be overly critical and think that my reviews of other properties show that I have been generally satisfied with other rentals with minor exceptions, but there are issues with this property that I feel potential renters should be aware of, and I have tried to describe those in a matter of fact way.
