Yankel' s place is all you need for a stay in Paris. Location wise- everything is handy. Supermarket just right outside the building. 3 metro station lines is roughly a 5-8 minute walk.! The neighborhood is quite lively.
Room size is just enough- had 2 large luggages yet we still managed to move around.
Just be ready to walk up 4 floors with your luggages- so my advise is to travel light. Otherwise everything else is perfect. Will definitely stay here again.
