The location is excellent (in the heart of the 11th arr) and the flat is very well furnished, clean, with terrific new kitchen and bathroom. The kitchen has been redone recently and as photos indicate it's nice, clean and has everything you want. It's got everything you need for a few nights, and is such a great address for walking, attractions of all sorts.
The downsides are: it's pretty small (good for 2 people, but 3 or more will be a stretch). And it's pretty loud. 1st floor apartment (1 above the ground floor), on a very busy intersection, right above loud bars and restaurants. The double windows insulate from noise, but it means you'll have windows closed all night long, which is not great in the summer months.
All in all, we recommend the apartment, especially for a couple.
