This hotel, despite being a very old building, is kept very clean with all basic amenities (towels, soap, hair drier, etc.). The breakast, while basic, was good and sufficient to keep me full until lunchtime. The staff were all very polite, and it is easy to contact the owner for any queries one may have (just message via the app). Also, the location is amazing, very close to the Jardin du Luxembourg and Notre Dame de Paris.
My main annoyance was the lift, which didn't always seem to work, but at least that got me to exercise a bit rather than be completely lazy - silver lining right there.
