I loved my stay at Emma's place, the location is a perfect starting point for walking to basically anywhere in central Paris or taking the subway. The apartment is quite small, as described, and there is noise from the stairs / nearby commerces. Nothing too bothersome as it was quite peaceful at night (more than I expected, since it's noted that it can be noisy in the description). The amenities are great for a short stay and if you don't plan to spend too much time in the apartment - I stayed a week and was working remotely part-time and it was just right. The hosts are very responsive and helpful, and the bed is incredibly comfortable. Overall it was great for what I needed and I highly recommend for 1-2 people!
