This feedback will be split in 2. There's Maxime the person, and then there's his apartment.
Maxime the person was delightful. Respectful, polite and made sure everything went smoothly. I have nothing but respect for him as a person.
Now comes the 2nd part. His apartment.
The apartment was ... horribly unclean, scratch that, health hazzard levels.
I'm talking years worth of mold build up, toilet in an utterly disgusting state, unusable unless you'd want an infection, stained (even blood stained) sheets, (they had turned brown), shower booth smelling like piss and brown spots, washing machine that wouldn't do the full cycles (as it kept making so much noise and moving that I had to physically hold the washing machine in place during the entirety of the wash cycle). And about the wash cycle, it wouldn't go through completely and would effectively leave clothes not completely clean. I had to use the washing machines at a shop nearby just to even use the sheets. I had to spend €120 in cleaning and hours worth of cleaning to get the apartment in a usable state. (And even then, my girlfriend and I ended up using rolled blankets as pillows because that's how bad the pillows where, and even had to put towels underneath us as we were uncomfortable sleeping on top of a massively stained mattress... There's unclean, and then there's health hazzard levels of neglect.
This is why I've tried to get a refund. I feel sorry for Maxime, but I'm pretty sure a host ought to meet a minimum health requirement before listing a palce. I feel like I got cheated by staying in that apartment. (And the Airbnb policy of asking for a refund in under 72hrs is BS for a city as popluar as Paris. Because even getting a refund won't help as you can't land a bed&breakfast or another airbnb on the spot in Paris in the middle of the turist season. So my option was to shut up and take it.
I'm going to seek some recompensation for what happened, as the apartment greatly impacted my stay and it was definitely NOT what I was expecting.
I'm sorry Maxime, I mean no ill for you as a person, but it's hard to draw the line, you really have to get your stuff in order and it's your responsibility to supply your guest with even the bare minimum of hygienic conditions.
As for the location, you can do better in Paris. The 11eme arrondissement is perhaps the least attractive arrondissement in Paris barring banlieues. Has pretty much nothing of note, historic value-wise. And being tied to the metro for anything means you're behaving as an utter. (going underneath the 11th and coming up in another, lavishly beautiful arrondissement with no experience in between = jarring.) I'd strongly recommend someone to go for other arrondissements, makes for a more enjoably experience.
