I was forced to download an app and create an account before I could get keys to enter the apartment (even though I had already paid for the apartment). The app is a proprietary app for Sweet Inn designed as a competitor to Air B&B. I find their tactic offensive. They are using the Air B&B platform, and then tricking me into downloading their own platform and forcing me to open an account with contact information that I would never willingly give to such a shady business. If it had been possible, I would have changed apartments.
The apartment was slightly overpriced, slightly oversold in the photos, and on a very noisy street. Our first evening (Saturday) we were each woken about 10 times from crowds and police / ambulance sirens. The location is fantastic except when it comes to sleeping because it's on one of the busiest one-way thoroughfares in Paris (along the Seine). The floors are also the most noisy of any floor I've ever encountered, make it hard to go to the restroom at night without waking the person sleeping in the livingroom.
The people working in the office below the apartment were friendly and helpful. They work for a company with a corporate culture that lacks morals. I can't even unsubscribe from their emails so I had to block them. Overall a very bad experience with Sweet Inn.
