Great location, amazing views, very well decorated and comfortable. This hotel beats most four stars (globally) and will be the only place I consider staying the next time I visit Paris.
Saint-Michel Notre Dame metro/RER station is literally across the road (lines 4 and B respectively), providing a direct line to Paris CDG airport and all major attractions. One of them, Notre Dame, is right outside the window providing great views that include the cathedral, the Seine, Shakespeare & Co. book shop and more.
Behind the hotel you've got the buzzing Latin Quarter, great for an evening stroll and a reasonably priced meal (make sure you look around though, it's a bit of a tourist trap). In front, the Islands are easily walkable and worth a visit.
Hotel staff were very helpful when I asked for help making a table reservation in broken French and were able to answer all questions regarding locations, travelling times, etc.
Paris is known for small rooms with terrible bathrooms. Well, the rooms aren't huge, but you won't need anything bigger. As for the bathrooms: very modern, clean, good shower, very pleasant!
You could easily pay double for less in this city - look no further.More
