This is an excellent place for your budget Paris trip, though tall people beware.
Justine was super helpful in our check-in even though we had some last minute changes. The place was impeccably clean and completely free of any pests (as someone who has a phobia around this, I was initially worried but there were no signs of anything.)
The 11 metro to Châtelet is the perfect subway line for tourists, and this apartment’s proximity puts you in easy reach of the core. The food at the square nearby is fantastic and affordable - try La Rigole’s couscous. Grocery stores are nearby as well.
The only caveat was the size of the washroom. We admit, we’re big guys (6’1” and 6’5”) so we expected to squeeze, but the bathroom is so small it’s totally unsuited for people of our height. The shower isn’t super comfortable and we had to sit sideways on the toilet in order to fit.
That being said, this is a place for a cheap getaway, not a luxury experience, and it does that extremely well.
