The pros are the location without a doubt. The studio was very well appointed and nicely designed with modern details. The pink was very flattering--it's a very cute place! Jean was also very helpful in helping us find the place. I had some confusion with the instructions on how to find the studio once you are in the building. He was kind enough to help us at 10:30pm due to our late arrival.
The cons: We really enjoyed our stay but were surprised by the air conditioner situation. We were experiencing a Paris heat wave yet the AC required us to keep the balconette window open so that the tube could vent out. This made it quite warm in the studio because we lost all of the cool air to the hot air coming in.
Perhaps it was just our room, there are eight others in the group. We only stayed two days and were out nearly the entire day, so it wasn't a huge issue for us BUT again, we specifically looked for a place with air conditioning because we knew it would be hot in Paris in July. Some visible wear and tear in the studio making it feel less elevated.
The value is fantastic and as I said the location is really great. The size was perfect for my husband and me. We felt very safe and it was in close proximity to excellent shopping, cafes, and museums.
