Standard was what I expect from Adagio. Clean, comfortable, well heated in winter, friendly and helpful staff.
Being 6 mins from the ReR line C is great as you can get to places like the Eiffel tower in about 20 mins of train time. Increased cost of being out of the Paris zone is well worth it. Just be aware that some of the trains are fast and don't stop at Ivry.
There is also a larger Carrefour about 7 mins walk away, which is cheaper the more local one. I didn't use the local restaurants as I am gluten free, however it looks like there is a good selection and these are likely to be more affordable than the ones in Paris.
Can be a little noisy with traffic as on a busy road, however I suspect the rooms to the back of the property are quieter, so if that is likely to bother you maybe request a room at the back. It is fine though over night.
Wifi was fine overall, however I did have some problems using Zoom on occasions.
A nice, economic option for a stay in Paris.
I really enjoyed my stay.
