The location in the 10th arrondissement is perfect, for us that arrived with the train at Gare de l'Est it was a short (10-minute) walk. We could easily walk to the places we wanted to see.
The guys in the reception spoke excellent English (my French is quite limited) and were very helpful and service-minded. We left our luggage with them both before checking in and after checking out. We had an issue with locking our door and were helped right away. The breakfast buffet was small but sufficient for our needs, with plenty of pastries and bread, jams, fresh fruit, granola, wonderful (wonderful!) freshly squeezed orange juice, and of course coffee. They also had eggs, sausages, different charcuterie, and cheese.
