This is a fine place if you are traveling to Paris, especially with a pet.
Location is good, and close to the central hub of Montmartre, with many cute shops and cafes lining the streets around the apartment.
Unfortunately, we had a terrible issue with noise the first day and night. We were awoken by extremely loud and unexpected drilling and hammering the entire first day (which continued into the second day, but luckily we already were up in anticipation of the noise). Spoke about this to the host and he did his best to speak to neighbors, etc. so that was appreciated. It did, however, mar an otherwise good time at the location.
Also, please note that there was only 1.5 rolls of toilet paper in the apartment, which was not enough for 3 people for 5 days, so consider bringing your own. Also, no wine glasses, only water/juice cups, which we found a bit strange for Paris.
