Pros: Very conveniently located near several cafes, restaurants, bars, and public transportation. Very quick bus or train ride (10-15 mins) to common tourist destinations, such as Eiffel Tower, Trocadero, museums, Seine, Arc, etc. Staff is very friendly and breakfast was included in our reservation, in their charming breakfast lounge. Staff is very friendly and helpful.
Cons: Beds are very hard and walls are very thin, making it difficult to get a good night's sleep. Though we stayed on the 5th floor, we could feel the underground train rumble under the hotel every few minutes. If you like very firm beds and are a very heavy sleeper, it might work for you. The hotel also requires all guests to leave their room key with the reception each time they leave the premises and collect their key when they return - very odd policy.
