Boris' place was great! He has it all hooked up with a bunch of modern tech - you can watch a movie via projector, turn the lights on with different lighting schemes to match the mood, and his wifi is pretty fast.
Boris' place is pretty close to Sacre Couer and right down the road from Monmarte. There is a wonderful bread place nearby Grenier au Pain (something like that) and there are a million little restaurants, patisseries, charcuteries, etc. nearby if you don't fancy going all around the city to find something good.
Getting to the metro takes 5 minutes.
The only odd thing was the bathroom in the same place as the shower. And the showerhead is one of those handheld ones. I rigged it to hang off of the shower bar and spray down on me, that worked pretty nicely.
