An expensive howebver good apprtment in a central location in Paris.
You should take into account that the owner is a difficult person. We did not have proper contact before arriving. Since we arrived late, after 1 pm, he charged us highly (150 Euro) for late check in and wanted 200 Euro for leaving the suitcases for 6 hours as for late checkout. So if you go there make sure to set everything with him upfront.
