If you are staying in Montmartre, this is a **perfect** space. My wife and I stayed two nights while visiting Paris, and while we weren't in the apartment a ton, it was comfortable and cozy to return to, and had everything we needed to get ready for the next day. Its location is in the heart of the neighborhood, provides a beautiful view of the city, and is convenient to return to whether you're coming back on the metro or taking a stroll around Montmartre. The apt has gorgeous exposed beams and a super comfy bed, which were lovely to come home to after walking 500 miles all over the city every day!
The host Alexandre was wonderful--he literally watched for us to arrive from his window, at which point he ran down, welcomed us warmly, and helped us with our bags upstairs. We followed several of his recommendations and they were spot on. My wife and I have both said multiple times that staying here was one of the reasons we enjoyed Paris so much--Thank you Alexandre!
