The Hotel du Temps has 22 rooms and one suite, located in the 9th Arrondissement and within 15 minutes walk of Paris Freemasonry Museum and Galeries Lafayette. Paris Opera and the Sacré-Coeur basilica are also within 1 mi (2 km).
Very close to metro lines -- poisonnaire station is about 3 minutes away. No stand up shower. Room was very compact, hardly any space apart from bed.
This was an incredibly well designed hotel, with all the charms of a french b&b but with the efficiency and attention of a boutique hotel.
