This apartment had a lot of positives and a lot of negatives:
The view is really truly incredible once you poke your head out far and look left from the window and so really only one person can enjoy the view at a time, while standing up. The light show is just the most magical thing you will see hourly , especially the last one at 1am. The apartment is the most dreamiest building with a hysterically small lift but we just appreciated having a lift since those are so scarce in Paris. You do need to take one flight (about 20 steps) from the 6th floor to the 7th. Check in was very easy as long as you follow instructions. Uber is easy to catch as the street is a limited road with little traffic. The location of the unit is impeccable! Just literally seconds to the base of the tower with tons of cafes and boulangeries in the area.
However, our stay in the unit could have been easily a 5/5 if the host just took a little more attention to easy fixes. The biggest thing for me is cleanliness and quality of bed. Albeit I know it is a sofa bed, a lot of airbnb's we've stayed in had pull out couches or futons, all very comfortable or reasonably so. But, this one sinks down and has no support in the springs> I felt like I was in a college dorm. It really isn't too too bad if you stay here for just one night, but if you want to stay longer, it can be problematic. The rug in the space is very dirty and there was hair everywhere. Sheets were stained and towels well used. Thankfully there was tons of toilet paper but the toilet has this odd flush to it where toilet paper gets stuck on the sides because such little water runs down. For how often this place gets bookings, it's a pity the host doesn't just spend some of that income to invest in a proper bed that's not so worn out and dirty.
I have stayed at a lot of Airbnb's and I rarely complain, but I was very disappointed with the lack of care in the bed and cleaning quality. Most importantly, disappointed with the ability to enjoy the view from the room. Mind as well just go downstairs and enjoy it in person, which is why this place gets 5/5 for the location!
