A great place right in the centre with loads of bars and shops around, yet still rather quiet. The apartment is well equipped, all the kitchen-basics you need are already there (unlike in many other places). There is a big supermarket right next door.
The only thing you have to keep in mind: if you are tall (like me) the beds are only 1.90 m long, so they might be too small to share. And the matress is a bit hard.
Apart from that I fully recommend the place. I never met Renan in person, but our correspondende via mail and SMS was friendly and he always reacted promptly.
