We had problems booking somewhere to stay in Paris: two cancellations on Airbnb for this trip before we made this booking. This flat is not someone's home, so having been caught out twice before, we were fairly confident the booking would not be cancelled and that proved to be the case. So that was a good start!
The flat is very well located, close to a number of Metro stations. You can get to most places in 20 minutes or less by Metro and RER. Lime scooters are also available nearby (but watch out for the taxis: they're not good at sharing the bus lanes).
The flat itself was clean and the air conditioning was appreciated during the hot nights. No air conditioning in the bac bedroom, but if you leave the door open a little the cool air circulates quite well. A separate w/c as well as the bathroom is a big plus if travelling in a larger group or with teenage girls!
There is a good bakery just around the corner (Bo & Mie on rue Saint-Martin) and the Monoprix supermarket on Boulevard Saint-Denis is handy.
