We had one of the top floor rooms. We had to climb a flight of stairs after the (tiny) lift, but the view was worth it! We could even see the Eiffel Tower over the rooftops. I chose it because we wanted to stay in Paris, and feel like we were staying in Paris! The room was small, but with the lovely view and charming sloped roof with exposed beams, it really did feel like we were somewhere different.
They claim 2 stars but it felt better quality and value than other 3-star hotels we've stayed in in Europe. The front desk is 24/7 and the staff were all very friendly and helpful to us. They have free wifi and we had a good signal all the way up on the sixth floor! We didn't have the breakfast (10 Euro pp) as we could eat for way cheaper from the many patisseries nearby.
Location is great- easy walk across to Notre Dame- and the area has a variety of cafes, restaurants and bakeries. We walked everywhere on the first day but there are two metro stops nearby and a bus stop just around the corner.
We had a nice stay in Paris.
