We had 2 day stay at the loft and it was just wonderful.
Very spacious and clean.
Easy to go from there to the metro or walk to places, because it feels quite central.
There for Loft has some nice details and a good cityguide made by Jean Gabriel. Just one thing that you might not think about, if you go with 4 people like we did, there is only on bath/toilet.
I would highly recommend this stay, you will enjoy it.
