Clean, great location, great views of Notre Dame outside our windows, easyc bilingual communication with staff. The elevator is small (urban life) and operates well.
Breakfast is offered at the Belloy, its sister company, directly across the street, for 18€. Make sure to check to see if your reservation includes it or not. The breakfast offers café/cocoa, a variety of bread, cheeses, hard boiled eggs, juices, granola, fresh fruit, etc.
There is Monoprix, a grocery and department store with great selection.
Close to metro, restaurants, bookstores, shopping, museums, great location!!
