Handsome apartment; quiet courtyard view on relatively quiet street. Great location in Marais. Nice bathroom, comfy bed, great kitchen, clean, secure, charming. We really enjoyed our stay and would recommend the apartment.
My only quibble (minor) was: (a) it wasn't abundantly clear when viewing the apartment on-line that the bedroom and living room were separated by partial wall -- not a big deal for us, but if you were expecting more privacy you should know.
Frederic was very responsive to our questions -- often calling / e-mailing / or texting within minutes of any request.
