Zazie Hotel has a great staff that is friendly and helpful. Upon checking in, the woman at the front desk (didn't catch her name) helped us settle in to the cafe for breakfast them spent about 10 mins going over the city map with us and showing us the best routes for the bus tour.
The hotel itself is a 3 minute walk from the yellow metro line, which goes right to Bastille and several other central landmarks. Great location - not in the middle of everything, but situated in it's own neighborhood with plenty of restaurants nearby.
The room is small compared to major hotels, but it is comparable to most hotels in Europe. The room was decorated nicely with designs on the walls. The bathroom - similarly small, but suitable - including the shower (I suspect a large person - in height or girth - might have a difficult time with the shower, though. The twin beds were clean and comfortable.
You can add on the breakfast "buffet" for €9 a day. It includes cheeses (delicious!), breads, tea, coffee, jams, assorted fruits, different milks, orange juice, oats, etc. Very simple breakfast and a convenient way to start the day.
I would definitely recommend the hotel, especially for short stays .
