The location of the appartment was great. 15-20min walk to Louvre. The neighbourhood was pretty good. No problems at all.
The appartment is a lot smaller than it looks like in the pictures - I believe around 20 sq.m. The so called bedroom (where the bed is located) has no windows, but is practically a room 2x3m where only the bed fits.
The appartment was clean, but not extremely clean (dust in the corners), towels were clean. Loved that we had hair-dryer.
Also, it was kind of cold.
The communication with the host was efficient and prompt.
