Vu and Kim's place is a great location in the heart of Le Marais. It is surrounded by dining (falafel shops, bistros, crêperies, wine bars, etc.), shopping (high end and smaller boutique), and multiple lines of the métro - we walked to and from St. Paul easily for all of our destinations while in town.
The apartment itself is a third floor walk-up that sleeps 2 comfortably, and would be a bit of a cozy fit for 4 as there is not much in the way of open space when the pull out sofa is unfolded and travel luggage is in the room along with 4 people moving about.
The bathroom/wc is separated into two rooms - one with the toilet and the other with the sink and tub. Neither of these private spaces have a ventilation fan.
The main bed is lofted above the studio and accessed via a step ladder, it did not feel tight or cramped with 2 adults up there, but there was a slight amount of effort going up and down.
The TV has a streaming device attached which has access to a large base of channels (french and international channels), as well as netflix capabilities.
The large pair of windows provided a wonderful amount of light and breeze to the space and opened up to some people watching below - though they were also the conduit for all of the street level noise in the mornings which start around 0600 (trash pick-up, street cleaning, produce deliveries, etc.) The morning bustle would be inconvenient for anyone hoping to sleep-in beyond this early hour as the commotion starts rather early and does not dissipate. And since the apartment does not have air conditioning sleeping with the windows shut during the summer was not an option.
There was a bottle of wine waiting for us upon check-in which was an enjoyable little plus. Vu and Kim were also very accomodating of our earlier check-in to drop off bags and communication with them was a breeze for any questions/concerns.
