This apt is located in a neighborhood that I would describe as "in transition", surrounded by old fabric, trimming and clothing stores with a few lingering sex shops, with newer shops and restaurants popping up, such as the one year old Disney'ed up recreation of a Parisian style brasserie (in the space previously occupied by a clothing manufacturer), which was adorable and very convenient for our morning café and croissants and late night drinks and snacks.
The building in which this apt is located itself is very run down and not clean, but the apartment itself has been redone. The main issue, as others have noted, is the street noise below the windows at night, making it impossible to keep the windows open, but unfortunately we could not get the a/c unit or one of the provided fans to operate. The new windows do completely insulate against the street noise--thankfully.
Check-in and out communication with the agency, located a few blocks away, was fine. The apt was not very clean when we arrived, however.
