First of all, I'm sorry for the mouse but this is possible in an old town. The problem was solved by traps (I had indicated the next day the store in the street of the apartment that sells the product). Since the following tenants have noticed anything. This problem has already happened once in 5 years.
For the washing machine, the porthole is a little hard indeed, it is necessary to insist but it works without too much effort despite everything. The other tenants used it without any problem.
As for the bed, it was changed this week, slats had been broken by former tenants a month ago.
On the shower, great for Paris, it is very clean and I like it: there is confusion with the fact that the paint on the ceiling of the shower peels off, which is not dirt. A painter comes in September to remake the painting of the ceiling.
The number of solicitations on the part of this traveler has been very important. For the communication on the subject of the mouse, my answer was the following day: it would have been difficult the same evening to solve the problem, knowing that the mouse did not enter the apartment but in a closed cupboard.
I think a hotel will be very good next time for this traveler but it will have to pay double as minimum for the desired level. Once again, I repeat that we are in a real AirBnb (I live part of the year in my apartment) that respects the rules of the City of Paris and not "fake hotels" prohibited in this city.
