We loved our stay in JJ's cute apartment. The locations is wonderful and makes it easy to travel around Paris by foot or metro. We also loved being able to see the Eiffel Tower from our little home.
JJ was a good communicator before and during our stay. He was on holiday so we did not get to meet him, but his sister met us to give the key and was friendly and helpful. Despite being on holiday, JJ was responsive to messages sent during our stay which we greatly appreciated.
The apartment is stocked with everything one would need. It is small but makes good use of the space. I was initially bummed by the soda bed, but it was actually the most comfortable sofa bed I'd ever slept on. Also should be noted that previous guests have griped about the Internet speed but we found it to be very fast and reliable.
Overall, we strongly recommend this space. Great location and even though it is small it seems to be a good value in a expensive city like Paris.
