Alex's apartment is spacious, convenient and comfortable and Alex is a very gracious and considerate host. In fact in all respects bar one this apartment is a great place to stay.
Alex well knows his apartment's achilles heel, however, for he alludes to it in the listing, and I have to say I disagree with his positioning on this. I have stayed in many apartments in central Paris over the last five months and can confirm that the noise levels in this one are far from the Paris norm.
I stayed two nights. On both mornings at 6am an articulated lorry pulled up just below the (2nd floor) apartment window to noisily unload a lot of its contents, and on both mornings at 6.30am refuse collectors arrived to take away the leftovers. This happens directly below a window that looks double glazed but seems to have no sound insulation. Maybe I was unlucky, but this has the look and feel of a daily routine. Added to this the apartment walls are very thin, so when people are having a social in a neighbouring apartment you will know about it. Which is a shame, as in all other respects the place has a lot going for it
