We arrived around midnight after a short distance walk from the Gare de l´Est. The escalator is quite small for a stroller, but helpful for our arrival at the forth floor. Our room had one bed about 1,20 m wide and a extra couch to sleep on, which was very comfortable for the small child and one adult. Pillows and blankets all well! The bathroom was tidy, the toilet flush very special, but not very strong though. The windows could open to get a glimpse of Sacre Coeur, but at the same time let the evening sounds come in (restaurants and bars on street). We did not use the aircondition, since it was too humming. The interiour was wonderful, all new and stylish! Breakfast was standard besides the fresh croissants and therefore quite expensive. WiFi worked well. Two Metro-Stations are close (Grand Boulevards/Cadet), about 20 minutes walk to trainstation or Montmartre.
Conclusion: We would come back!
