Our stay at this flat was ok.

Pros: great location. A block away from the metro and about a 5 minute walk to the Eiffel Tower.
Very safe building.
Lots of ATMs, small supermarkets for basics a block away.

Cons:
Check in was a mess. We were so tiered but couldn't rest because there was a cleaning lady inside our room talking super loud on her cellphone. It was very awkward.
The room is not as nice as pictured. And the drawers were full of clothes and underwear the belong to owner. Lamp was broken too.
Wifi was super hard to connect to.
TV was also weird. It had cables running across the room in which we tripped on a couple of times.
Bath tub was weird too.

Overall this location is great just to sleep in, but there could be a lot of improvements. For the price we payed we could have stayed at a more comfortable spot. I don't think I would be back.
