The hotel is quite easy to reach from the train station and is located in the centre of Paris. The main attractions of Paris (Louvre, Tour Eiffel, Montmartre, Versailles etc.) are really easy to reach.
The personnel is really kind and will help you with everything, so just ask them if you have any doubts.
The only downside is that the mattress was too soft for us and the AC was always put on a really low level every day (you can change it but at first impact the room was really cold).
Other than that everything was perfect, would recommend.
