Clement's apartment is perfectly situated for exploring Paris. My boyfriend and I spent 5 nights poking around cafes, museums, and restaurants and were always happy to come back tired and content to Clement's home. The bathtub is definitely an added bonus, but make sure you read the instructions on how to use it.
I would recommend staying here, however I wouldn't suggest it for anyone who is not steady on their feet or has leg problems due to the stairs to the lofted bed.
