It was decent. Very close to train stations and metro. Host Laurent was awesome and very accommodating and easy to communicate with. Check-in process is great.
Neighborhood seemed safe but isn't as nice or safe as many Paris areas. Place wasn't dirty, but also wasn't especially clean. Most bedroom and bathroom doors didn't open, stay closed, etc. Linens weren't nice and seemed old and not very clean.
Overall if you want a solid place to stay and don't mind the little things it's a good place for a good value close to Gar du Nord/Gar de l'Est.
