I had a nice stay at a very well located place. It is indeed a typical Paris studio in that it's quite functional and not very spacious, but if you only need a place to sleep while travelling in Paris, it's a great option - and the balcony is very nice. Samuel was very welcoming and available in case I needed anything, and check-in was reasonably smooth. Be warned there is quite a staircase to ascend if you're carrying heavy luggage though!
