Place is a good small apartment to crash in if in Paris for a couple of days, mainly for its handy location.
As another couple of reviews have highlighted though, the place was not the cleanest.
Also, when I highlighted the dirt that was visible in the flat (and sent photos), Yu's communication became quite bizarre and defensive. Having been too busy to flag these issues up during my stay, I sent a polite message which stated that while I had enjoyed my stay, the lack of cleanliness was a negative factor. As he has done with previous reviews, he suggested that I was taking out other frustrations in my life on my negative comments of his apartment, and that I was 'complaining like I had spent €1000 per night' (I just answered honestly when he asked how my stay was). Budget customers shouldn't have to put up with unclean places.
Also, Yu messaged to say that no towels will be provided after booking. This includes hand towels. Useful to know before booking.
All in all, quite cheap and in a good location, not much wrong but could have been cleaner.
