Pros: LOCATION!!!! Close to metro station, walking to Notre Dame was very easy, bathrooms were great with a separate WC with the toilet only, restaurants nearby. Cons: the endless construction noise was maddening (8am hammering wake ups!), the drunks were walking and yelling until 5am, bar deliveries nightly at 1am - directly under the bedroom windows, there was no A/C which would have been ok except there is zero ventilation. The main living space with 2 pull out couches (main sleeping space) was a very humid 95 degrees the entire time we were there - morning and night, the W/D nor dishwasher were working, and bring your own hand soap!
Also, there is NO ELEVATOR - it's located on the 2nd floor with a full flight of stairs to climb.
I would only recommend staying here if you are a group of 2 (the bedroom windows opened wide so much cooler), after the construction is done (this will take months), or going during cooler months so you don't need to leave the windows open and you can actually use the living room. I expected more for the price.
