Vinicius's places was absolutely lovely, and set in my preferred area of Paris. Near enough to the Latin Quarter for the easy access to late night crepes and dancing, but not so close that you have to fight the crowd's to get home or put up with the noise.
The space is split into two floors with the main bed and shower room (washer inside) being on the second floor; and the living space, pull-out bed, kitchen, and toilet room being on the main floor. We had three adult women stay, and never felt crowded, especially considering the sizes of many flats in Paris. The pull out couch was about as comfortable as one would expect, and my friend ended up just sleeping on it as a regular couch instead. The bed upstairs was delightfully comfortable. But most impressively was the very spacious, well pressured, clean, always warm water shower!! My friend's even took a couple of baths to soak their weary bodies from all of the walking.
The last thing I will say, is though check-in is extremely smooth, they meet you at the door, they are very particular about check-in times, and charge a late fee. We had the unfortunate experience of being delayed on our flight over, arriving later in the evening, and though it was out of our control, still had to pay for a late check-in. So just be aware.
All in all, we were extremely happy with our stay there, and would highly recommend it to anyone! Enjoy Paris!!
