Joanna's flat is very nice. Surprisingly large, a nice kitchenette, comfortable beds & sofa-beds, and so centrally located. The street is very busy and noisy (which I expect and quite like in a Paris location!) but the windows block out sound completely.
The only downside is that I chose this listing specifically because there was air conditioning and a washing machine available. However, neither worked well and this was very disappointing. The problem with the washing machine is just that it's quite old and can't drain the water properly, so we ended up more or less needing to hand wash the clothing we put into it. And the problem with the AC is that, like most old apartment buildings, the wiring in the place isn't configured to properly run it. The unit had to be kept at 22 C/ 72 F in order not to short out, and the motor put off so much heat that it was counterintuitive to even turn it on (it seems on the verge of burning out and needing to be replaced). There are only windows on one side of the flat, so we couldn't get a cross draft and it was quite stuffy.
If those last two things aren't important to you, then this is a perfect choice.
