Positives: The apartment is in a great location in the Saint-Germain-des-Pres areas. It was about 2 blocks from the Odeon metro stop and you could walk to Notre Dame in about 20-30 minutes. There are 3 bedrooms (one bedroom where my wife and I slept, a very small bedroom where my mother slept, and a kids room with a trundle bed where our two kids slept) plus a couple living rooms (one with a futon), a small kitchen and two bathrooms (but one toilet). The apartment is okay overall but the Airbnb photos definitely put it in its best light -- some rooms have a fun modern style but also there is lots of clutter and some of the faucets, appliances, etc seem a bit run down.
Negatives: I had a very poor impression of the property management company, which felt like it was run by teenagers. During check-in (he was 20 minutes late even though I later found out their office is a block away), the host didn't introduce himself, say hi to my family, welcome us, etc. Not such a big deal but bad first impression. When I asked if he had recommendations on local restaurants, he just said there were plenty and I could look around myself. Towels were cheap and when I asked for more it took a day to get them. It was a crazy heat wave (about 97 F) but I was told they had no fans. Then the next day I was told they would try to bring some fans and more toilet paper but they never came by. I had two different days where I was sending 2-3 emails asking for towels and toilet paper but got no responses for a full day. Basically, bad service. Only when I checked out did they bother to tell me their office was 100 meters away and I could stop by for towels and tp as needed (something they clearly should have mentioned during check-in).
Overall the apartment was fine and a good bargain but poor service and we would stay at a different place next time.
