This is indeed in a fantastic location and within walking distance to many of the attractions in Paris. I read all the reviews at the time I booked the place (around May 2022) so I have set my expectations appropriately. However, new reviews had come in during June 2022 around safety concerns with the defective door, and we encountered the same issue during our stay.
First, by reading the check-in instructions, I recognize the inconvenience of having to pick up the key from a location (laundromat that is only open during day hours) about 10-15 minute walking distance from the property. I already expected this inconvenience and was able to plan for it. We arrived into town by train, so I just planned our walking route from the Metro station, to the laundromat, then to the property. No big deal, even though we were walking with our luggage in tow. Pretty common in a tourist place like Paris.
We arrived late in the day and didn't feel like going out again that night (except for one of us to buy some take-out food). We didn't become aware of the door security issue until the following day.
The location of the place is fantastic. The Seine river is just a couple of blocks away and the Louvre is just across the river.
The renovated apartment is wonderful. Be aware that these buildings in Paris are very old, so the stairway to the apartment is very narrow (very common for the buildings built at that time) and I wouldn't hold that against the property. Since air-conditioning is not popular in Europe, the apartment had a very small table fan. I think an investment should be made for a bigger upright fan and guests would appreciate a bigger fan. Aside from the fan, we didn't find any shortcomings with the amenities. There are small grocery shops within a couple of blocks where you can buy any necessities for a longer-term stay.
The biggest issue is the door security issue. You essentially cannot lock it from the outside. You can lock it, but the key has to be left inserted and cannot be pulled out. I looked at the problem and it seems that the door lock has been installed incorrectly. Perhaps it was some renovation early in 2022 because there wasn't a complaint about the door before June 2022.
To check if this has been fixed, once you pick-up the key, enter the front, and up the stairs (remember that in most of Europe, the ground floor is numbered as the 0/Ground floor and the next floor above is the 1st floor, followed by the 2nd floor, etc.), and facing the apartment door -- try pushing open the door without using the key. If it has not been fixed, then the door would just open inwards. This is a safety concern, because other tenants in the building could just go in to the apartment. If you visit the attractions around the city, you are essentially risking your belongings being stolen.
Looking at the door lock, I can see that the problem is the LATCH BOLT of the door knob doesn't engage into the STRIKE PLATE. The strike plate was installed into the frame misaligned with the door, possibly just by a few millimeters. Either the strike plate needs to be moved a bit, or the hole in the strike plate should be widened a bit so that the bolt engages with it. I think that the reason the key cannot be pulled out is because the bolt does not engage into the strike plate.
And with the problem, communication with the host or property managers was difficult. We even escalated the issue with Airbnb and they also could not get in contact with the host or property managers. The issue was not fixed within our 4-day stay in the property.
As I write this review, I see recent reviews (June 2022) discussing the same problem. I'm hoping the host gets this fixed before other guests book this property.
