Location Location Location! Layout of apartment is a bit odd.
If you are wanting to stay in the Le Marias area, this location is spot on. Close to many restaurants and bars, shops and ease to get around the city.
Pros: 1) Location is always key when visiting and exploring a city and this location is fantastic. Aside from shops, restaurants and bars just steps away from the Hotel De Ville metro stop and about 12-15 min walk to Les Halles for access to many metro lines. 2) The bed is super comfortable. I find that most European hotels/airbnbs the beds are quite hard, but this is true comfort and the weight of the comforter was perfect. 3) Well equipped Kitchen- the kitchen albeit small had everything that you would need for short stay- kettle, nepresso machine, plenty of glasses and plates, refrigerator, etc. It would have been great to have a roll of paper towels or napkins for use but remember to pick some up at one of the Franprix close by. 3) Wifi worked very well, no issues. We didn't watch the tv, but did turn it on and it works, but you aren't in Paris to watch TV!
Cons: 1) 3 floor walkup- this was clearly stated in the post, so no disagreement there, but it was quite narrow and difficult to get the large suitcases up as we were traveling for 10 days. Keep this in mind if you have trouble lifting. 2) The layout of the apartment was odd and smaller than it appeared in the post, as there is another staircase inside and the bathroom with the toilet is on the stairs and you have to walk directly onto the stair to leave the bathroom. We got used to this after a few days but felt it could pose an issue if you have any mobility or balance issues. Likewise there are a few steps off the bedroom down the staircase to the bathroom, be careful to not miss those. 3) the bathroom with the shower is quite small, my fiancé is tall and had trouble getting in and out of the shower given the door opens into the shower and there's little space to get in and shut the door.
All in all, if you are ok with stairs and have no mobility or balance issues, this place provides all the needed amenities and the location is great! And we had great communication from the hosts all through the process- immediate response when we asked a question and provided us with details for self check in with no issues.
