The studio apartment is extremely clean, the bathroom is nice, and the bed is very comfortable. Since it is in a courtyard, it is also very quiet. It's in one of the best locations in Paris -- the city is at your fingertips. The apartment is a perfect point from which to explore.
The only downside: we were there during a heatwave, and it was unbearably hot as the courtyard trapped heat. Just something to consider if you are there during summer months.
