Location, location, location! Easy to locate and situated less than a block away from a metro station, our entire group (4 adults) agreed this rental was great value for the money we paid to rent it! There were several stores (organic & regular super-market grocery store) just a few feet away, along with cafes & restaurants that made it easy to eat out.
The flat is equipped with everything anyone would need & clean (laundry, tv entertainment, microwave, fridge, dishwasher, ironing board). The only thing it didn't have was an oven, in case you were interested in baking or picking up a pizza from the supermarket. Other than that - it was perfect for our entire week's stay. The hosts were extremely helpful & cooperative - they even sent over recommendations for our stay including free museums to check out and local eateries (Le Coude Fou)!
Some side things to note: 3 flights of stairs make it a struggle for anyone a bit older and/or out of shape. This is the only way to get to the property, so just make sure you are aware of this before booking.
Also, during the night activities, since you are located in such a premium downtown spot, you will most likely hear noise from the bars and motorists. Not enough to disturb sleep, but enough to potentially keep you up if you're not ready to pass out yet.
