Solid apartment for Paris in an excellent Neighborhood. Quiet yet in the heart of the 11th. Generally a nice unit for a short stay.
Downsides are that it is a corporate managed unit (although managers are very quick and efficient with communication) The cleaning was not very well done. The apartment is very sparse and completely IKEA furniture so not super comfortable. Kitchen set up is very sparse on tools, plates, bowls, utensils, pots, pans etc. Also what is there is of very low quality. If you are only going to reheat meals, it's fine. But I wouldn't try to cook here, it will frustrate you.
If you know the drawbacks and they are not important to you, then, it is an excellent place to stay.
