We chose for Marais location- great near restaurants and cafes and park. Walkable to Seine and metros convenient. Fun to watch street below.
Entry hall funky and stairway very narrow (lived in French student apartments for years so lots to compare to).
However, bright and clean remodel inside. Two back rooms small but quiet, and front br street noise but ok for our group. One bath is through front br so harder to share. As others have noted, bedside tables and area lamps/clips would be nice. Decor was impersonal. Wifi worked.
Never met 'Alexandre' but Guest Ready responsive to requests and remote key codes worked. Overall fine for our family who wanted a few days in Paris together.
