We have stayed for 3 days in here. The hotel's location was absolutely great, you could easily walk to M13 and M9 metro lines. You have to get off in Miromesnil station and walk 3 minutes to get the hotel.
M13 was very useful to connect to Champs-Elyssee, Concorde and Madeleine, and M9 was pretty useful to connect to Sacre Coeur-Montmartre, Eiffel and St. Germain-Sorbonne-Pantheon. If you want you possibly choose to walk too, it takes 35-40 minutes to Eiffel and 40-45 minutes to St. Germain.
The room was a bit small but who needs a huge room just to use for sleeping at nights? Paris must be explored in every hour and every minute, so don't keep yourselves at the hotel room. The personnel were helpful and positive as much as they can, you can ask them everything.
Thanks to everyone in D'Albion for helping us to have a great holiday in Paris.
