Very clean room and bathroom, peacefully quiet hotel in a convenient location and good wifi. Be aware one wing has no elevators and the spiral stairs are narrow. They offer a breakfast spread for a price - currently €15.
Very close to Pyrénées metro station and not far from Belleville metro station. Easy to find. Very interesting neighborhood with lots of cafes and world cuisine. Carrefour city grocery store and McDonalds just around the corner a few minutes away. No microwave or fridge in room, for those who might need that.
Some people may find the rooms small if they are used to American hotel rooms, for example. But Parisian hotel rooms often tend to be smaller. Had a perfectly good stay - nice hotel and safe but interesting neighborhood.
Would avoid Belleville station late at night. Not unsafe, just a bit unsavory crowd around there sometimes. But across the area, cafes and pubs are filled with young people late into the night. The convenience stores also stay open late and have most things travelers might need.
