Beauquartier is a great place! Yes, it's above the subway but a little rumble and noise was part of being in Paris. We were three couples and liked the fact we all had a bathroom and two toilets in the hallway. The rooms are cosy and beds are comfortable with enough room for suitcases. Wifi was great and having a washing machine on a long trip was excellent as well. The position was perfect for getting around Paris especially with the Metro being so close, but you can walk to many many places. If you want an apartment with a Parisian feel, go ahead and book as you will not be disappointed.
