This apartment is right in the heart of the action of the Canal St Martin / Oberkampf neighborhood. Worth the climb up 4 flights: Bright & airy apartment, your bedroom with street view, king sized bed & closet, & friendly English/Spanish/French speaking local (her bedroom on the opposite side of the flat & she works weekdays). The bed takes up alot of the room, but you'll enjoy hanging out in the living room & if the stairs aren't enough there is even a treadmill & stationary bike, just ask!
Be aware it's on the 4th floor with no elevator, and there is no television! Besides that: You can use a fully equipped open kitchen, big living room, bathroom with toilet and shower. It is a really pleasant apartment in a building dating from 1835 (but everything works :-) Towels and sheets provided.
Your "roommate" for your trip is a friendly Spanish friend who has lived locally for 9 years, she speaks English, French and yes, Spanish! I am just downstairs so can help with any info you need.
