The hotel’s location is perfect. The metro station next door can take you pretty much to everywhere. The prissy bus station is also quite close to take you to the airport. If you are in the mood for walking, most sites within 20 minutes of walk. Many restaurants around. AND safe! I stayed at this hotel last time I visit Paris and very satisfied; hence, directly booked with them again this time.
The staff also very kind. I arrived early before 11am, and they still got me checked in with a nice room, 4th floor facing the city, great view! (Tip: the 5th floor does not have elevator; hence, if you travel with a lot of luggage, try to avoid it.)
The room is small, but you are traveling in Europe and given the great price the hotel offer, it is expected.
The only thing I don’t like is that the heating is far too warm; but I heard that it is the case in many hotels this winter. So not a complain towards BW itself.
